While I mostly agree with your first paragraph, I don't see Nintendo as the innocent and awesome third player. They are certainly doing well in terms of sales numbers right now, but they've proven time and time again that they're hostile towards their fanbase (and I'm not talking about pirated games here).

I also don't see how the Switch brought a "fresh, intuitive control scheme" to the table. The hybrid console concept was the first well implemented take and quite a few people certainly like that flexibility, but in my opinion the best way to play Switch is on a TV with a bunch of "Pro" controllers.

And in terms of games, I think Nintendo makes consistently good games (for the most part), but most of them are also very safe bets. You have your 2D platformer Mario games, 3D platformer Mario games, some fighting and sports Mario game spin-offs (again, nothing new), and a bunch of games set in the Zelda universe. Splatoon was something else, but we're at Splatoon 3 by now as well. I personally thought Mario Maker was the most "revolutionary" title in somewhat recent times. I enjoyed some of these games especially for their coop (or pvp) experiences, but there wasn't much in there that truly surprised me.

YMMV of course, I know a lot of people absolutely loved the Zelda games for the Switch for example. Nintendo games are also pretty much feature-complete out of the box, which isn't something you can say for a lot of these live service games popping up everywhere.

I personally think indie games or games from "large-but-based" studios are more important than ever and that's where I got the most original and memorable experiences from in recent years.
