Your thoughts on the Switch are actually very reasonable, rather than anti-Nintendo. Many people would agree with you, even Nintendo fans I feel.
As for games, I would consider BotW and Mario Odyssey, even if you're not really interested. I've found it to be very fun personally, and one of the highlights of the system. Xenoblade Chronicles 2 looks good, and if you like JRPGs, it may be something you like. If you like shooters, you may enjoy Splatoon 2, though it is rather unique for a shooter, so it may be worth trying out.
And as for Puyo Tetris, I have the game too, so if you'd like to try some online MP, I'd be down for that.
Dance my pretties!
