While not all games will be to your liking, there are currently over 700 games on the eShop.
There are physical games (not 700, as most are digital indie games), but the problem is many stores don't carry a wide selection of the physical games and will only carry the selections that have already proven themselves to be top sellers since they were hurt by the Wii U sales.
But I agree, look to see what games are out there. Expect a lot of indie titles, but there are major releases just about monthly. With over 700 games on the eShop, I'd expect that there would be something there that you would like.
I bought my switch at launch and play it more than any other system that I currently own.
My son also has one and does mix it up with PS4 and Wii U games since he has online friends that he plays with.
