Thinking of 2021 for a summer time trek, probably will only get a weeks permission/child care, so looking at a trek* of 4 days with a day either side for travel.
For one week only, I'd clearly stay at home
Iceland
Given only one week, it seem's most sensible to limit the travels to the (very busy) SW of Iceland.
Good thing is, there are beaten tracks (like the Laugarvegur/Landmannalaugar, Gullfoss, Geysir, Skaftafell, Þingvellir), but it's easy to go off them.
I'd not bother with the Laugarvegur unless you go late;
Into the first week of September the camp ground at Landmannalaugar starts to get empty (as does the famous trail). In the second week those working at the mountain mall return back home, the busses stop running mid September too. If you're an experienced outdoor person, you're comfy with strong winds and infrequent snow storms in the higher regions, the first two September weeks are best. There's a reason why the Laugarvegur is so busy in July/August. The landscape is very unreal. Add on the Skógar trail (over the Fimmvörðuháls) and depending on weather and fitness you have a lovely 2 - 5 days trip. Although walking south you'll not end the hike with a bath in a hot spring (which is in Landmannalauger - hence the name), it's easier to shorten the hike and you end up at the ringroad with easy hitch hiking and regular busses, camp grounds, hostels and hotels. Best to make a reservation in Skógar.
If you plan to go earlier, there are many other fantastic multiday hikes in the Fjallabak besides the overused Laugarvegur/Skógar trail.
Get the maps and put your own route together.
Some established routes that come to mind:
Eldgjá - Skaftá - Langisjór. Rather easy, but can't be always done, as the river Skaftá runs off a sub glacial volcanic system and bursts every now and then.
Laki - Grænalón - Skaftafell. Tough hike, only for very experienced hikers.
Hellismannaleid trail. Easy
Then in the central highlands:
Further afield there's the Kjölur trail or Kjalvegur, yet still easy to get to from Reykjavik.
Hvítárnes - Hveravellir - Varmahlíð. Close up to glaciers (but unlike the Grænalón trail, no glacier crossing involved), yet in the middle of the "desert". The classic route ends in Hveravellir (hot springs, 3 busses/week) but the really remote part only starts at that point and goes all the way up to the Fjords in the North.
This one is great because you travel past touristic places in the south to get to the starting point, with stops to look around (Geysir, Gullfoss, Kerlingarfjöll). Closest town at the end with regular busses/flights is Akureyri.
Mountains of Kerlingarfjöll - many shorter hikes than can be made into a longer one.
Nyidalur, circuit around Tungnafellsjöküll.
The E side of the galcier (Jöküll) is also know as Vonarskarð.
Unfortunately no more busses along the Sprengisandur, which go past the huts at Nyidalur, but regular 4x4 folks for a lift.
moderate route over broad ridges, down smelly valleys with hot pots, over a small pass and onwards to (boring) double tracks which will take you back to the huts.
Eastern highlands:
Askja trail or Oskjuvegur (I only know the area around Askja - but know it well from 3 visits).
Surely not as easy to get to the start/from the end of the trail, but also into September there are still some folks about which can give you a lift. Seems to be very straightforward like the Kjalvegur, yet more remote and a starker desert. Askja is one of the bleakest places in the Highlands, yet magically colourful. Closest town with regular busses/flights is Akureyri.
South Eastern Iceland/highlands:
Lonsoraefi - Snaefell.
Very highly recommended. Similar but no quite as difficult as the Graenalon trail. For experienced hikers nothing crazy. Mostly easy glacier crossings, days of trackless hiking with crazy views. Colourful (rhyolite mountains, mosses), even birch forest, glaciers, no crazy fords a bit of desert and stunning waterfalls and mountains. Ends at the huts at Snaefell - the highest peak outside the Vatnajöküll massif and the most alpine looking one. If there's time left, the mountain Snaefell is a great hike in itself. With a bit of luck you can spot reindeers on this hike.
Starting point can be reached in one long day from Reykjavik by a very scenic bus trip and about 30 min hitch hike.
Ending point (Snaefellskali) will again require getting a lift, but with chances are big that you get this chance daily to Egilsstaðir.
Westfjords:
I've never been to Hornstrandir, but my girlfriend has and thus I know a few things about that region. There are many options for a few days out, but you need to rely on calm weather for many of the options, as starting and ending point can only be reached by boats. With a narrow window not the best idea. Totally different landscape again. Yet one you already have when ending the Northern section of the Kjalvegur.
Iceland is quite straight forward when it comes to known hiking routes. Off course you can go cross country and some of the above mentioned don't actually have a track you can follow in many places, but are just route suggestions - some have cairns. The density of tracks/trails is scarce. Norway is very different. Once you leave vegetation you often just have red marked rocks and cairns. Lower down there's always a tracks of some sorts to follow.
Norway
So many lovely spots to pick from. Again... To great thing about central Norway is, that it can be reached by train within reasonable time.
Central Norway
Breheimen NP
I found Breheimen Nasjonalpark to be very special. Bre = glacier, heimen = home. So, full of glaciers, but many multiday hikes without needing to traverse one. Full of options. Most at the upper end of moderate. You soon end up going over a 1000 m high pass where you'll be going over boulders.
Jotunheimen NP
Similar to Breheimen but busier, as it holds the highest mountains (very busy in summer) in Norway. That's why Breheimen is so lovely, it's kind of hidden behind it large, famous neighbour Jotunheimen.
Dovrefjell-Sunndalsfjella NP
A bit tamer than the two above, but just as magical. The right place to see muskoxes.
A wonderful blend of what Norways mountains are alike. Has a high peak (Snøhetta, 24th highest in Norway) with an easy hike up too - like Jotunheimen - yet without the hordes.
hmmm... just to name a few. All are equally easy to get to. You can leave home in the morning and spend the first night of the trip in the tent out on the fjell on the same day. But then you miss the fantastic breweries in the cities.
One place I've never been, but looks really special is Femundsmarka NP.
Northern Norway
Lofoten.
As with some places in Iceland, this area is otherworldly. Nothing less.
Most hikes are steep and slippery - it's not a place for folks who struggle with heights.
Rago NP
A little jewel.
Have so far only brushed the boarders when hiking across the Scandies (coming from Sweden; Stora Sjöfallets NP through Sarek NP and Padjelanta NP) but would love to spend some more time there.
Talking about Sweden. The three above mentioned NPs are well worth a visit too. The most inaccessible point in Sweden is actually between Sarek NP and Padjelanta NP. Been there, done that

Sarek's often considered as the last wilderness of Europe - which isn't quite true. The raindeers roaming the Sarek are "herded" by the Sami people.
I could provide tons of photos from all those places mentioned, but have been speed tiping away for more than an hour now, so need a break.
I really do hope you can arrange to go for more than just 4 days, but with this here you'll surely find some really nice options.
I've must have spent more than a total of 3/4 year hiking, biking and kayaking in those areas and can help with further planning, maps etc. if needed, also since my last visit to Norway was 2018 and to Iceland 2019.
