My solution for this has been on my Linux machine, using keyd, to swap alt and super, and map super+c, super+v to copy and paste. (I also map super+L, super+R, super+T and super+W in Firefox to the control- equivalents using keyd's per-application bindings functionality)
Switching it at the terminal emulator level should work fine for every CLI/TUI though, right? Just have your terminal send 0x03 when you press C-S-c and copy selected text on C-c. I haven't tested it but I'm sure that alacritty, wezterm, windows terminal and probably tmux can do this.
When I was learning neovim over the summer, editing the configs was the perfect way to practice editing. Lua is a simple language and forcing myself to do the config from within nvim created a positive feedback loop where I wanted to keep using the editor more and more.
