The reason there are so many RPGs is because for everyone one of them, someone said "My RPG itch is not getting scratched. What would?". There's no shame in not digging any particular one. 5e does have a lot of players so it's easier then most to find a game, but that doesn't mean you need to play it. The one caveat to playing other games is that often you either need to convince someone to run or run it yourself.
If you're looking for something close to D&D but isn't 5e, I'd suggest 13th Age. But from your description that might be too close to D&D in terms of mechanics. On the other hand, it might be just a fresh take on it you want.
Looking at the list of what you like, it seems the fantasy genre is where you want to stay. Luckily, there are plenty of games out there. A previous poster mentioned Dungeon World, and anything Powered by the Apocalypse (PbtA) will have a very different feel than D&D. That will have a lighter, more narrative feel as well as putting much more control in the player's hands about the direction of the campaign.
If you like crunchy on the other hand, tightly integrated with the setting, there are a number of different versions of Warhammer Fantasy out there. Just reaching as far as I can in the opposite direction as DW that's still well known.
Fate & Fate: Accelerated Edition (FAE) both can do fantasy, and there's both published and free fan-created content for shaping the rules to match the flavor and setting you want. Savage Worlds and other general systems can do the same.
There's lots more options out there, especially if you want to explore other genres as well. Take a vacation from D&D and explore new games.
Best of luck!
