Pretty much first-party Nintendo games and a handful of independent games. I had the same desires as you, so all I really had and played and liked was:
Animal Crossing
Tears of the Kingdom (Breath of the Wild was good but TOTK is basically the same game but 1000x better and after playing it I have no desire to go back to BOTW)
Super Mario Odyssey
Clubhouse Games
And if I had known it existed while I still had the thing, I would have gotten Switch Sports.
