I have some suggestions on Scandinavia. As a starting point I took the post by Tab911 earlier in the thread (
https://forums.civfanatics.com/threads/development-map-suggestions.632861/page-29#post-15483384) where many good suggestions were made.
First, some suggestions on terrain changes:
-The red areas on the map are moorlands. Compared to the earlier suggestion I added more to Norway and the middle of Sweden. Moorland looks awesome IMO, and is great for Scandinavia!
-Added three forests to southern Norway (marked by yellow). The southern parts are the most heavily forested areas of Norway in reality, and together with the Trondheim area make up the places in Norway where forests have commercial importance.
-Removed some forests from Norway (white areas). As a reference on Norwegian forests I link this:
http://www.borealforest.org/world/world_norway.htm
-Added island feature east of Kalmar representing Öland.
Second, resource placement. I may have gone overboard, but of course not everything has to be included.
Denmark:
Horse (2W of Köpenhamn): Represents the Jutland horse. Early versions of this breed may have been used by viking raiders in Britain in the 9th century. During the middle ages they were popular as war horses and exported to the continent. Also good work horses.
Pig: The modern pig industry in Denmark is very large. Can be a late spawn to give extra population in Denmark.
Cow: Already placed.
Amber: Already placed
Sweden:
Iron (2W of Stockholm): Represents the Bergslagen area, which has substantial amounts of iron ore, and has been the heartland of Swedish industry throughout history.
Copper (1N2W of Stockholm): Already placed. This represents the famous Falun mine.
Wheat (1S1W of Stockholm): This can be a late spawn to increase population. This area has some quite good spots for agriculture (by Swedish measures), and wheat is grown here modern times.
Stone (2S1E of Stockholm): Both Öland and Gotland have easily available stone. Stone from Öland was exported to the Baltics during the middle ages for the castles of the Teutonic order. May also be nice if one wants to build a castle in Kalmar.
Sugar (On Malmö): Possible late spawn (mid-late 19th century or so) to represent sugar beet production in Scania and Denmark.
Deer (2N1W of Stockholm): Already placed.
Fur (3N of Göteborg): This area is unusually rich in wild animals usable for fur.
Rare earth (1E of Sundsvall): Represents findings from the Alnö complex, which seems to have high concentrations. Of course, there are also other places where rare earths could hypothetically be placed.
Potatoes (1W of Luleå): Potatoes are one of the few crops that can be grown this far north. Can be spawned in the 19th century to give some population growth and enable working on the forests/iron.
Fur: (1N1W of Luleå) Already placed.
Iron (1N2W of Luleå): This area has huge amounts of iron ore. Mining started here in the 18th century IIRC, but transportation was very difficult. It didn't start to really get going until the beginning of the 20th century when railroads were built to Narvik and Luleå, from where it was then shipped further. Since then, it is the dominant source of iron in Sweden.
Norway:
Silver (1N of Oslo): Already placed. Represents the Kongsberg mines which were opened in 1623. I can't find anything on silver mining in Norway prior to that.
Sheep (1S1W of Oslo): Moved so that they are not reachable from Göteborg, which preferably shouldn't be super attractive early on IMO.
Fish (all three): Norway is a huge fishing nation, and its Atlantic coast is extremely good for fishing.
Aluminium (both): Norway doesn't mine bauxite, but makes aluminium from it using hydroelectricity. It is one of the largest producers in the world. These areas seem about correct for some of the industries.
Horse (2N1E of Bergen): Represents the Fjord horse, a very old breed and favoured by the vikings both as a workhorse and war horse.
Oil/whales: Already placed by Tab911.
Fur (2N1W of Oslo): Already placed.
Finland:
Cow: Replaces horse.
Deer: Already placed.
Copper: Represents the Outokumpu mine, which opened in the beginning of the 20th century. I think it's better to have this than to replace it by a swamp, as Tab911 suggested.
Gold: Finnish Lapland has several large gold mines, and Finland has recently been the number 1 gold producer in the EU. Exploration started in 1868, but it is only in the last few decades it really got going. So maybe not so relevant.

Iceland (not pictured):
Added aluminium. Iceland produces significant amounts:

Finally, as core area for the vikings I suggest to use something like this:
