The problem I have is when all of the available subclass to too specific and don't allow me to continue the classes generic flavor. Sorcerer is the best example. Either I start growing scales on by face or I explode at random moments. There's no generic "inner magic" subclass. I get to choose between the colorful butterfly master and dragon-man, neither of which are flavor neutral enough for my liking.
I think that the Wild sorcerer was supposed to be the generic version of the class. You didn't have some kind of outsider mess with your family at some point, you're just magical. But because it comes with the narrative of being not in control of your powers and it's wild magic table is a pretty gonzo mechanic it doesn't feel generic. Which I think it a pretty big failure for the class because I agree with the bulk of your post that game feel is a very important part of playing the game.
