Pianist here. I see where you're coming from, but I definitely do also rely on the different shapes of keys to know where I am without looking. I've been learning to play the button end of an accordion and personally I find the uniformity makes it harder. But maybe that's just what I'm used to.

As an aside, I find c major a horrible key to play in, again I think the uniformity makes it harder and less ergonomic, but the same thing makes it easier to teach to beginners hence why everyone starts there.

Absolutely.

Another data point: I play the organ, which involves playing a large keyboard with your feet (https://en.m.wikipedia.org/wiki/Pedal_keyboard). The structure of black notes is crucial to being able to play without looking (which is important because you’re simultaneously doing various other things). Concretely, I couldn’t imagine playing the organ without being able to slam my foot into the right hand side of a B flat in order to know that my foot is on top of the B. If you watch an experienced organist’s feet you’ll see them do this all the time.

I also find C major horrible.

This is pretty eye opening to me, I would have never thought anyone found C major more difficult to play in than other keys. To me, difficulty is directly proportional to the amount of stuff in the key signature, but that may be because I've never had proper education (~5 years of lessons as a child from a very casual teacher).

The way we happen to notate music doesn't help to endear people to f sharp major, certainly! If you keep practising all the scales and try to learn to do more by ear/improvise, I'm pretty sure you'll end up enjoying other keys more.
