Boardgames

I'm not sure it fits perfectly, but clank is one I've really enjoyed with 3 players. It shines with 3, but 2 can play as well. It's a dungeon race at its core, so there's slightly less going on with fewer players.

Another that might fit even better is wingspan/wyrmspan. They also shine with 3, but are more about your own buildup, pretty chill, and even work down to solo play.

Edit: if you like card games, especially euchre, California Jack is one I found to be pretty fun and unexpectedly interesting with two people. The scoring is a nice twist. It's a trick-taking game just like euchre, but you also tally up your cards at the end. It lends pretty well to some light strategic play. I also have to mention Golf, just because I've had a good time with it. Card games can be classic and cozy.
