Neovim is a modal text editor forked off of Vim in 2014. Being modal means that you do not simply type text on screen, but the behavior and functionality of the editor changes entirely depending on the mode.
The most common and most used mode, the "normal mode" for Neovim is to essentially turn your keyboard in to hotkeys with which you can navigate and manipulate text. Several modes exist, but two other most common ones are "insert mode" where you type in text directly as if it was a traditional text editor, and "visual mode" where you select text.
Neovim seeks to enable further community participation in its development and to make drastic changes without turning it in to something that is "not Vim". Neovim also seeks to enable embedding the editor within GUI applications.

Just use the NeoVim defaults and then if something is bothering you or missing, rebind it. Most of the defaults have been totally legit for decades, and everyone speaks in terms of them. At the end of the day, your job is to build muscle memory one way or another
But yeah rebind caps to esc at the OS level
I've bound it to esc when tapped and ctrl when held, no more bending my pinky or thumb in half in an attempt to press ctrl.
