I tried to keep the keys mostly the same but the one I could never get used to was command + c/v/f/etc. It's just too awkward a combo for fingers. Using pinky for control on the left was much better ergonomics. So I swapped control and command keys.

I’ve done the exact same thing. I remember switching to Mac 20 years ago and the very first time I contorted my hand to use the copy shortcut and thinking…lol nope.

This definitely must just be a “what you’re used to” because I find using ctrl for a modifier to be far more “contorting” than moving my thumb a bit to the left or right of where it’s already naturally sitting for the space bar, and my thumb is a “stronger” finger than the pinky so it also just feels easier on the hand. So much so infact that I remapped the right hand command key to ctrl in emacs (with the usual capslock-> ctrl remapping for the left hand) just to make it more comfortable.

You're probably right!
