I can say offhand that No Man's Sky put a lot of extra time and effort into their Steam Deck support so that definitely works. Otherwise your best bet is to check either the Steam listing for a game (check the Deck Verified rating. Anything rated "playable" or "verified" should work pretty seemlesly on any Linux gamingPC) or https://www.protondb.com/ (a user run listing of the compatibility of different games. A good resource and often has some troubleshooting advice. Unfortunately it can often have outdated or just inaccurate information as it's all based on user reports. Still usually a pretty good indication of compatibility.) There's no indication on either regarding Starfield compatibility. Given that it's probably too resource intensive for the Deck it may not get as much special attention from Valve as something like Elden Ring (which ran better on Linux than any other platform after it was out for a few days and Valve had added a patch to Proton to fix an issue that the developers took longer to patch in the game itself.) Chances are pretty good it'll work though (assuming your hardware can run it.) The Steam page for Baldur's Gate 3 says it's Steam Deck Verified so it'll just work so long as you launch it through Steam. Here's the protondb page for reference https://www.protondb.com/app/1086940 . Crusader Kings III, Rimworld and Stellaris apparently all have native Linux ports so, while you may find reasons to prefer running the Windows versions with Proton, you don't actually need to check for any special compatibility. They just are Linux games.
It really sounds like I've been sleeping on recent Linux compatibility then. I remember back in the days of Wine it seemed more a PITA than was worth it.
Thanks so much for the in-depth response!
Yeah Steam/Proton and other tools like Lutris make it so you don't really even have to touch Wine for most stuff, it's all taken care of for you. Gaming on Linux has come a long, long way in the last few years.
Well, Proton is a patched Wine. Nowdays many games support Linux natively.

Proton also includes DXVK.
DXVK works in vanilla too
