I have a lot of games which were enjoyable 100% of the time, but none which I played for over 100 hours. I’d be absolutely exhausted if I was in “oh neat haha wow!” mode for that long, personally, my dopamine receptors would be fucking fried.
Good luck with your search, and below I have some which fit your criteria outside of the 100 hour requirement.

I am not certain if the android version has controller support but I do know that they ported it to consoles and PC and those versions indeed do have controller support
Sky: Children of Light is a delightful game from the creators of Journey, and plays sort of like a Journey MMO
It has a splendid soundtrack featuring vocals from the ever talented AURORA, and beautiful visuals. It is also a great social experience, putting a focus on fostering connections and community. It gets regular content updates and its just super cozy!
I think its likely that goty will go to Helldivers 2 or Black Myth: Wukong, both of which I think are aggressively “OK”. Goty awards are largely a popularity contest, after all.
A steam deck is my recommendation. I have a £2000+ gaming PC that is now practically collecting dust because of my steam deck. Being able to just game anywhere in my house, from my bed, from my couch, from a chair in a sunny spot in my garden, has been a game changer in a way I didn’t expect. I’ve owned handheld consoles before but none of them have hooked me in the same way.
The fact that I have my entire backlog of PC games available to me and don’t have to buy into a new ecosystem (like the switch or previous handhelds) is a huge bonus, but the absolute winner here is the variety of input options and the degree of customizability, as well as the fact that its a PC, so I can fuck with the refresh rate and the clock speeds and all that - extending the battery life!
The portability also has me being a bit more social with the other occupants in my home. I can play some low-focus game on the couch while they watch TV, for example, and we can chat and so on, as opposed to being isolated to the room where my PC is.
If you think there’s any chance you’ll get a kick out of being able to just grab your deck and go loaf somewhere comfortable to game, its a no-brainer to me.
