Found this guide of Switch Metroidvanias.
These play like first person point and click games. They are highly polished and relaxing fun, set in hugely imaginative game worlds with often stunning artwork. You can tell from how many I've bought that these are really enjoyable games, especially if you played PC games in the 90s
THE BEST
Nightmares from the Deep 2
Enigmatis 2
Grim Legends The Forsaken Bride
Demon Hunter Revelation - exceptionaly generous
Family Mysteries Poisonous Promises
Family Mysteries Echoes of tommorow - Terminator 2, the point and click version
Endless Fables Dark Moor
Dreamwalker
Scarlett Mysteries
Dark Arcana
THE REST
The Secret Order Returned to the Buried Kingdom
Queens Quest 3
Queens Quest 4 - like 2D Elder Scrolls
Persian Nights 1 and 2 - Prince of Persia the point and click version
Grim Legends 3 - this one is average
Abyss The Wraiths of Eden - Bioshock replacement
Kings Heir - like a 2D Elder Scrolls, a touch short
OTHER DEVELOPERS:
True Fear Forsaken Souls 1 and 2 - excellent, horror themed
AVOID:
Lost Land series by five-bn games as the cursor speed is unacceptable

Found this guide of Switch Metroidvanias.
Hmm they mention that Monster Boy has 8 bit platforming! This is not true at all. There are some tricky platforming section, but they are nowhere close to the 8 bit era of finicky platforming. Heck Hollow Knight has much more and harsher platforming than Monster Boy.
Also the rest of their list is kinda whack.
Dead Cells is not a Metroidvania. It is a rogue lite with some Metroid elements. Still one of the best games on the Switch.
Cave Story is not a Metroidvania neither is Owlboy. Shantea Pirate's Curse technically is, but there is no interconnected map. They are kinda seperate levels with a level select screen.
Also Axiom Verge is a Metroid clone, but I just find it annoying to play. Not really a fan.
And Ori and the Blind Forest is just meh. The combat is bad and so is the platforming.
Steam World Dig 2
Hollow Knight
Monster Boy
I assume this thread was made for my benefit, what with the "damming" first sentence. 
Thanks for the copious recommendations. I don't buy as many games as I used to (and that still wasn't many then), so I try to be picky. I've learned that nostalgia is a very bad thing for me, especially because it isn't impetus enough to make me actually play the games that cause it. I still enjoy metroidvanias, as Hollow Knight is demonstrating to me, but I think that a big part of the reason I'm enjoying that game as much as I am is the art, music, lore, and world-building, which remind me of Dark Souls (perhaps my favorite series). I looked at some videos of Axiom Verge, and the 8-bit, monotonous graphics put me off. I've been through Cave Story years ago, but don't really feel like replaying it. I'll be trying the Ori games on Game Pass at some point. Not yet sure about Sundered and Dead Cells.
Right now, the only indie games I plan on buying are Hollow Knight (I've been playing on Game Pass, but want to own it), Stardew Valley, Blasphemous, the Bloodstained games, and Rivals of Aether. Beyond that, my time will be completely occupied getting through RE: Village, Halo Infinite, Elden Ring, Metroid Dread, and the next Zelda. Waiting for info on Callisto Project. I'll have to come back to the lists you guys are making when I'm feeling like more indie stuff, though. Thank you.
