Try experimenting with alternative terminals such as
https://wezfurlong.org/wezterm/ which I've used and where I remap all of
the keys to pass through to Emacs vs. letting the terminal application
abscond with functions like Command-C. I can share my wezterm configuration
off line if you're interested. I still remain mostly GUI on macOS but
occasionally use the terminal, and especially useful for running Emacs via
ssh on a remote computer (vs. tramp).
