You might want to consider leaving ‘M-q’ bound to
‘prog-fill-reindent-defun’ (introduced in Emacs 30, see
NEWS: C-h n) and simply binding C-c q to ‘fill-region’, or
one of the function keys F5 through F9.  Remember that Emacs
reserves ‘C-c <single character>’ and F5-F9 for user
keybindings, so your binding will never be overridden by a
future version of Emacs.
