Also a few more since the emulators list is split in a weird way and I missed them:
- For MSX: 真・魔王ゴルベリアス 先取り横スクロール面
- For PICO-8: #hasicontent, Celeste Classic 1 and 2, Slipways Classic, Dusk Child
Dunno what systems are made for the device, but checking a list of included emulators in a so called "Onion" operating system, I see a few other devices being listed, so if you don't mind, here are some more:
- For arcade: the other Metal Slug games up to 4 (have yet to play further), The King of Fighters 2002
- For MS-DOS: MegaRace
- For PC-98: コテ・DE・メクール
- For NES: Böbl, Micro Mages, Nix: The Paradox Relic
- For Genesis/Mega Drive: Wonder Boy in Monster World, Tanglewood
- For NDS: Shantae: Risky's Revenge
Avoided all plot-heavy titles, even when they may have long sections low on plot.
Maybe Celeste Classic? Apparently someone made a homebrew port of it to the GBA.
There's also Final Fantasy VI, which can be played kinda with the brain "on automatic" on quite a few sections as well as having overall plenty of places to save.
And since you'll be emulating them, if your device has save states features, Shantae for the GBC could be a good pick too. It is harder and less save-friendly than FFVI, but with save states, it should be better as a pick and play title.
And although focused on speedrunning, the impression I got from the homebrew Augury Red Code is that it is also nice if playing without having to focus too much on it.
Metal Slug 1 and X, and also Gunbird, all 3 released in the PS1, also benefit from save states to be more "pick and play".
Libretro folks are going to take the code of any maintained emulators anyways, so people don't really need to port it. Also didn't follow any news from Libretro's side, but considering Libretro's founder's past interactions in license changes of emulators the project benefited from, I can't help but wonder if he/she threw a hissing fit at the Duckstation folks as well.
Agreed with Magician and RmDebArc, and besides that, it could also be for the challenge, for the enjoyment, or because the vision of the dev only works in such a platform. And with emulators that allow commercial use around, the developer can also publish his games to modern platforms without having to rebuild the whole game.
If an Android program¹ is available elsewhere DRM free, open source, FOSS, etc., go for that instead, even before confirming the presence of this new DRM / social engineering tool in the given program. And if the program itself is not available, look for alternatives. And to make researches a little easier, some APK resources from the top of my head besides F-Droid and Github are Humble Bundle, Itchio, Patreon and potentially any Github alternative.
¹ "app" should never have replaced the name already adopted for no good reason

A few more (SFW) I forgot:
- https://www.gog.com/#giveaway (when a giveaway is present, it just scrolls you to that part of the front page)
- https://gaming.amazon.com/games (a cleaner redirect to
https://gaming.amazon.com/home?filter=Game) - https://www.zoom-platform.com/search/ (filtering in the site is still lacking, so my solution is a set of Ublock Origin filters)
- https://store.epicgames.com/en-US/browse?sortBy=currentPrice&sortDir=ASC&category=Game&count=40 (sorting by lowest price first - UbO helps here too)
- https://www.gog.com/en/games?priceRange=0,0&hideOwned=true (showing only the freebies, permanent or otherwise, from the whole catalogue, and filtering out what the user already has)
- https://randombundlegame.com/ (not directly useful, but maybe people can use it to keep an eye whenever another massive bundle pops up)
Of the NSFW ones, first the DLsite ones (so many because the store is split in multiple sections, and so much noise in the links because filters are hardcoded into them):

Should I list the NSFW resources too?
As much as GOG/CD Projekt have more than their fair share of problems, usually their versions of games work, can be preserved, don't require as much bloat, launchers included, and usually don't require 3rd party validation. And like others said, besides Wine and related, and installing through Steam as external games, you can also install stuff very easily through Heroic and the sort. So I'd say it's the better option indeed.
It has native screenshot functions, yes, but they are highly compressed. Iirc, there's a tool for taking uncompressed screenshots, but given the watermark in the screenshot, it's most likely the native function.
