I use this:

   (completing-read
    "mode: "
    (apply-partially
     #'completion-table-with-predicate
     obarray
     (lambda (sym) ;; predicate
       (or (get sym 'derived-mode-parent) ;; most modes
	   (get sym 'custom-mode-group) ;; ada-mode
	   ;; FIXME: leaves out fundamental-mode, maybe others
	   ))
     'strict)
    nil ;; predicate
    t ;; require-match
    (symbol-name major-mode) ;; initial
    history)

as the FIXME: says, it leaves out some.
