My top answers are of course Kerbal Space Program, Dwarf Fortress and Stellaris.
However, all those have been mentioned already, so, to add something new to the list: Pathfinder: Kingmaker. It is currently my favourite cRPG.
Edit: Since you mentioned “Great Linux ports”: Kingmaker has a game-breaking bug in the Linux version regarding Gamepad input. However, as long as you play it with mouse and keyboard (as the gods intended - insert PC Master Race meme), the Linux version is working perfectly fine. However, if you plan on playing it on the Steam Deck, you might want to play the Windows build.
