I use tmux's scroll/select/copy/paste with vim bindings

Alacritty has this too, but I have never tried it because I use tmux.

Good point - perhaps this belongs much more in the terminal emulator layer. I will have to investigate the options there!

Tmux is a terminal emulator layer. It even has its own terminal type. (Well, shared by `screen`.)
