I really liked Let's go Pikachu but probably that's mostly because I loved pokemon as a child. Legend of Zelda is great (any of the games really, Breath of the Wild was the last I played so not sure about the newer ones but older ones were always good), Super Smash Bros or Fortnite if you're into multiplayer games. Mario Kart is always good too.

I've heard good things about Tetris 99, if that's a game that appeals to you. Doom Eternal is a great first person shooter, if you're into that.
