You literally have the exact same list as me I just have pokken as a demo right now and have Odyssey. Nightmare mode was so sweeet and then I got bored because you need so many power moons to leave toadstool kingdom and I got bored haha but this is a list of the games I want maybe you will enjoy this list since we have the same games which means probably similar interest!
If you dont like Splatoon trade in yours switch and get a PS4. You aint going to like any other quality games Nintendo offers, since we dont rly on curse words, gore and violence to sell games.
