• Finland: Everything except Southern Savonia.
• Sweden: 8 out of 21 counties (Blekinge, Gotland, Kalmar, Norrbotten, Södermanland, Värmland, Västerbotten, Västernorrland).

Finland doesn't seem to open or close for specific regions. All of Norway and Sweden is currently open, and everything closes on Monday, except that people living in the vicinity of the land border can cross the border close to where they live. Finland seems to look at the country you are arriving from, and this makes it harder to open certain regions. To my knowledge, it's only possible to enter Finland from four Swedish regions (land border: Norrbotten; ferries: Stockholm and Västerbotten; flights: Stockholm/ARN and Västra Götaland/GOT), two Norwegian regions (land border: Troms og Finnmark; flights: Viken/OSL) and one Danish region (flights: Hovedstaden/CPH). It is therefore useless to open and close other regions apart from those seven as everyone else would transit through one of those.
