I remapped tmux to control-\ (which didn't conflict with anything in emacs that I cared about). It kind of sucks to hit that in a non-tmux shell or one without my config file though ;). Control-space is mark in emacs (even though I am using vscodium these days - I do fire up mg for quick things). It does make it a two handed chord (left control) but it's quite fluid for me.
