Mario + rabbids, pokemon legends, zelda:BOTW/TOTK (pick one they're both pretty similar and have their pros/cons), Mario Wonder, Mario Odyssey, Pikmin 4, Cadence of Hyrule (zelda spin-off of crypt of the necrodancer), zelda:links awakening remake, Mario rpg remake, and Bayonetta 2 (can also play on wii u emulator, 3 isn't as good)
I've been playing Mario Wonder and Mario RPG both are great and run very well. I tried BOTW but I think the framerate was capped at 30 and I couldn't figure out how to increase it
FWIW, the Switch is a fucking amazing console. Don't let the "but it isn't as powerful as my PS5" bros convince you otherwise. There are top notch games on Switch.
