Here's a little bit on everything (Non-Zelda) I've played, in the order they appear on my menu right now:

Fast RMX - A good racing game. The frustrating AI and godawful online netcode drag it down a bit though.

Graceful Explosion Machine - An awesome arcade-like shooter. Everything about it is fun, and it's pretty challenging trying to get high scores. Probably my favorite non Zelda game so far.

VOEZ - This is definitely the most unique Switch game right now. It's a touch based rhythm game also available for Android. It's not the most complex rhythm game you'll play, but it holds up.

I am Setsuna - I'm fairly mixed on this one. It's not a bad game at all, but it plays it really safe and never really stands out amongst other JRPGs.

Puyo Puyo Tetris (Demo) - It's Tetris, and it's Puyo Puyo. They're great fun apart, and great fun mixed together. I forsee myself playing the full game for a long time.

Has-Been Heroes - A brutally difficult roguelike. Hard to figure out, but pretty fun once you do. Surprisingly deep too. I'd only recommend it to hardcore gamers.

Blaster Master Zero - This remake of the NES classic Blaster Master stays faithful to its source material while adding some great improvements. It's pretty easy, but at $10, it's hard to not recommend.

Super Bomberman R - Oh boy. It's Bomberman, that gives it points, but it doesn't add anything new into the mix. Nothing to see here if you've played any other Bomberman title, especially compared to the other, much cheaper, alternative Switch games available.
