Hard to answer without more details but:

Pikmin series is good, starting with 3 deluxe is perfectly fine. (Its hard to describe but its awesome amd basically its own genera)

Minecraft will feel like a brand new game after a 7 year gap.

Mario Odyssey and Zelda breath of the wild are good.

Bug Fable is the spiritual successor of the paper mario franchise.

Xbox gamepass gets you what feels like a million games for a simple subscription, it includes many old gems like all of doom, quake, and newer games like Subnautica just generally has a long list that will make it a good place to explore many generas without actually getting invested in 1 game just to dislike it. (This is probably the best advice i can give, find services like this that basically let you download anything for "free" as part of the subscription so you can try out many different games to find what you actually want to play)
