This likely won't work. You need
(global-set-key [?\C-∫] 'backward-sexp) ; A-C-b
instead. Yes, it's an annoyance. You have to understand the
distinction between keys that emit characters and other keys (that emit
symbols).

These look just fine, yes.

Now that's very intuitive. A better choice (maybe still not totally
obvious to come across, but at least a bit more obvious to understand
when you read it):
(global-set-key [?\C-\;] 'comment-indent)

If you type C-x C-e twice in a row, with point right after the magical
number, you'll see alternative ways to write this number, one of them
being the one I used above.
