Persona 5, Monster Hunter: World and DBFZ are good pickups. (Could add Nier: Automata as well if you haven't played it yet.)
For me I've never been interested in playing proper games on the go, which is why I've only used my 3DS at home. I dable with a few mobile games if I'm on the train or in a waiting room, but that's just for a few clicks.
So when/if I get a Switch, I would always chose the PS4 version of multiplatform games anyway.
But for those who only own a Switch, whether or not the games end up on the system can matter.
My concern with third party games for Switch is not something that would affect me anyway, but rather something that could affect the appeal of the system.
This year at E3, out of every console level Japanese third party announcement for a major franchise or big Japanese studio, they were all announced for any combination of PS4, XBO and/or PC, but not Switch.

Jump Force (Bandai Namco)
Sekiro (From Software)
Babylon's Fall (Square Enix, Platinum Games)
And a day or two before E3 there was Dead or Alive 6.
While a Switch port of DBFZ was announced at E3, when there's an announcement for a big Japanese console level game, we usually don't see the Switch logo at the end of the trailer. Since we're over a year into the Switch's lifespan I don't think the situation will improve much. So I think the games those developers make specifically for Switch, such as Octapath Traveler, will be important when it comes to Switch's third party support.
But like I said, if you don't care about portability and you have a PS4 or in some cases XBO or PC, then it's not an issue.
Though what you said about the price difference between PS4 games and Switch games, I imagine Wolfenstein on Switch will drop in price quite a bit as well a few years down the line.
But on the subject of there being too many great games I still have yet to play that I don't have to pick up new games as soon as they come out, I can relate to you on that one. (I haven't even finished Persona 5.)
