Here's one approach:

(defun isearch-exit-mark-match ()
  "Exit isearch and mark the current match."
  (interactive)
  (isearch-exit)
  (push-mark isearch-other-end)
  (activate-mark))

(bind-key "<C-return>" #'isearch-exit-mark-match isearch-mode-map)

This binds a different key (C-return) to exit the current isearch and also leave the last match selected. This will work with isearch-forward-regexp as well, which is handy.
