To me, it's far more useful for a repeating
`C-a' (likewise `C-e') to move to the previous
(next) line beginning (end).

Just hold them down to zip along, just like
you do with `C-M-a' (and `C-M-e').  And nearly
every other backward or forward motion command.

In `misc-cmds.el' I define repeatable commands
`beginning-of-line+' and `end-of-line+' that do
that.  (And for my own use I bind them to `C-a'
and `C-e').

`M-m' is another that should be repeatable,
doing the same thing on the previous line.

In `misc-cmds.el' I define repeatable command
`back-to-indentation+'.  (Likewise, `forward'.)

(defun back-to-indentation+ ()
  "Move to the first non-whitespace char on this line, or eol if none.
If already there then do the same on the previous line.
This is a repeatable version of `back-to-indentation'."
  (interactive "^")
  (let ((opt  (point)))
    (back-to-indentation)
    (when (= opt (point))
      (forward-line -1)
      (back-to-indentation))))

(If someone uses both backward and forward,
`M-p' and `M-n' make more sense than `M-m'.)
