Most of the Paradox games support Linux natively. I play Europa Universalis 4, Stellaris, Crusader Kings 2 (haven’t bought 3 yet but it has native support), Hearts of Iron 4. Victoria 2 doesn’t have native support and I didn’t get Vic 3 but it is supported. Rimworld is native, so is Factorio.
Have a look at what you want to play on protondb.com and figure out if gaming on Linux works for you. Baldur’s Gate 3 has a gold rating (gold being one level lower than platinum - the best rating for non-native games) which for all practical purposes should work.
EDIT: I recommend installing Proton Glorious Eggroll in addition to the native Proton on Steam if you can’t get a game running with the native Proton despite protondb reports saying the game works. The installation is fairly straightforward, just read and follow the installation instructions on the page.
I switched to Pipepipe from Newpipe because I wasn’t sure Newpipe was being maintained. Pipepipe has SponsorBlock.
