How do you feel about Skyrim? I kinda want to recommend Morrowind via OpenMW, which should run fine on the Deck, but I guess both games would feel too much like DnD for you.
Undertale, if you haven’t played, might be fun.
You can also check out Trials of Mana, which is a remake of the SNES game and, unlike the remake of Secret of Mana, doesn’t seem to have any unpatched game breaking bugs. Other JRPGs that might be work checking out are the “Ys” and “Legend of Heroes” series, both should have plenty of games that play fine on the deck.
Lastly, Rune Factory, which is fantasy harvest moon (the farming sim that started it all, so to speak) with some light dungeon delving and leveling up.
The place’s name is e621, ends with .net, like the Microsoft thingy. Truly a den of debauchery that you should never visit. Quick, add it to all your blocklists!!

Bethesda could earn a significant amount of goodwill back by simply using OpenMW on a Morrowind Remaster and helping with its development, even if only for a year.
Or a fake limited time choice, as in, the character speaks as if they have to act or choose quickly! But if you don’t press anything, they’ll just stand there in a dramatic pose. Or go ahead and act as if you pressed the button anyway (Saints Row 3 had those)
