Since maximizing a frame changes the window size, couldn't you hook
into window-size-change-functions to achieve the desired effect?
Something like this perhaps:

(defun hide-titlebar-when-maximized (frame)
  (if (eq 'maximized (alist-get 'fullscreen (frame-parameters frame)))
      (set-frame-parameter frame 'undecorated t)
    (set-frame-parameter frame 'undecorated nil)))

(add-hook 'window-size-change-functions 'hide-titlebar-when-maximized)
