I do use most of those ctrl commands btw. I didn't know about ctrl-o, so thanks for that!
My little finger is much shorter than the rest but moving it a few mm to the left is easier than a large jump to the bottom of the keyboard for me.
For example, I use tmux a lot with ctrl-a.
A small movement of the hand left, jumping my little finger onto control (caps) and using my ring finger on A works really well for me.
Btw the first thing I do on getting a new mac is map the right alt key (or enter key back in the day) to control.
I hate having to press both keys with one hand for Ctrl key combos (ctrl-a being the only exception).
I also use tmux. I do a remapping to ctrl-s because I use ctrl-a (and ctrl-e) all the time to go to the beginning and end of lines. And let's be real, the normal behavior of ctrl-s (suspending) is not something I'm ever going to use on purpose.
But also I'm not using a mac.

Do you not use panes? In vim? Because I use those quite a lot.
e.g. Ctrl-o to pop out of insert mode for 1 command only.
or
There's loads more that are useful in Vim. Of course you've still got the built in Ctrl keys but having ctrl in place of caps is really ergonomic for me.
