Grid-based, dungeon crawler RPG (a mouthful, I know). The most recent titles in this genre I remember are the Mary Skelter trilogy, but the first game is about 10 years old already.
If you absolutely must get something from Google Play, I suggest Aurora Store, which acts as an alternative frontend for Google Play, so you don't have to have GApps installed.
If you have use for command line programs, Termux, a terminal emulator, is a great option, and it also works with root.
For reading eBooks, I also have a recommendation, Librera Reader (but I'll check the OP's recommendation too).
Material Files and Simple File Manager are great file browsing tools. But if you need a file browser for root specifically, I recommend Material Files specifically.
While the most recent piece of Apple technology I've used was a Macintosh 7, I've gone through similar issues with Android phones and desktop devices.
For Windows, the reliance came from the tendency of people (myself included) to avoid change, and Microsoft exploiting that, and with Android, because rare are the cases of commercial phones that don't come with Google's bloat.
But, upon switching to Linux and vanilla Android, as Nobuo Uematsu once said, "(...) the more limited people are, the more ingenious they begin to get (...)". So while I had lost most tools I had in my comfort zone, it was a good opportunity for renewal, of which I took advantage.
In lights of that, my recommendation is to "take the leap" and try technologies you're not used with, and see what you can learn from them.
This is just a hypothesis, since I never dug on the subject, but considering sparkling beverages overall, at least in my side of the globe (Brazil), use carbon dioxide, which, when mixed with water, becomes carbonic acid, which, when mixed with basic compounds, becomes salt, I'd imagine sparkling water would be a good way to increase salt levels in the body, which could perhaps be bad in your case, since you need water for medical reasons.
I agree it is an uphill battle, but it must start somewhere. Else, it only gets worse, and then movements against such abuses will get easily crushed. As I like to say, "the hardest part of a journey is the first step", but also "the future belongs to those who prepare now".
I use the Android app Librera Reader, since it's the best one I could find that is officially distributed outside of the Play Store (de-google, anyone?).
For ebooks, since Librera doesn't seem to be able to validate DRM (thankfully), I buy ebooks in DRM free formats, meaning I usually pend to Itchio, IndieGala, Fanatical, Humble Bundle, Story Bundle, etc.
Most Final Fantasy entries are either independent of each other, or very loosely connected, even more so on the mainline. Only straight up sequels, prequels and spin offs would potentially require having played earlier titles.
I'd recommend Mint, because, from my experience, it's pretty stable, UX is designed so terminal usage can be kept to a minimum (but you can still prioritize it if you want), support from programs is overall good, and it ditches snap. But worth noting that, if you need cutting edge features, Mint is not for you, as it seems to be the new Debian, where updates are traded off for stability.

Modded PS Vita, since upon modding, its scope of playable games becomes ridiculously high. Native games, PSP and PS1 games supported natively which can be expanded upon modding with homebrews and back ups of official releases you paid for, plenty of emulators for both the Vita and the PSP, wrappers for Android and PC games, as well as ports of game engines, getting released pretty much every week, and OS extensions for forwarding the Vita's screen to another device, making certain bluetooth controllers compatible, fixing/improving the system, and so on and so forth. It's a nice console. :3
The majority of posts on Reddit are also like that. Perhaps a curse of a feed-oriented forum (or whatever this type of social media is called)
