Yoshi’s Woolly World probably still counts. It got a 3DS port, but it’s a game whose visual identity is a huge part of the appeal, most of which is lost when running at 240p. In terms of games that probably should be on Switch, I think the Zelda remakes and Yoshi are the last ones. Kirby and the Rainbow Curse and Nintendo Land would both be hurt by porting to a system with “normal” controls, to the extent that they probably won’t bother.
