My favorite recent one would have to Kirby and the Forgotten Land. I've had hundreds of hours of fun with it, playing with my 5yo. It is very accesssible, but provides significant challenge in enough spots to feel like you've accomplished something. It is a big step forward for the Kirby franchise. It is also huge, considering the genre. And, most important of all, it is just super fun.
I have more time in it than any other Switch game, including TotK, which I loved, and MK8, which is infinitely replayable.
