I'd like to use C-c C-c for compilation and C; for commenting out code
in C/C++. These are the default in Auctex mode. Question is, is
there anything I'd break if use the same in C/C++ mode when writing C
code?
And is there a canonical way to unbind and rebind the defaults in
C/C++ mode?

I don't think so.

See help for functions `local-set-key', `local-unset-key' and variable
`c-mode-common-hook'.
For instance (untested):
(defun my-c-mode-common-hook ()
(local-set-key (kbd "C-c C-c") 'compile)
(local-set-key (kbd "C-;") 'comment-region))
(add-hook 'c-mode-common-hook 'my-c-mode-common-hook)
For learning more, read about "Hooks" and "Key Bindinds" on the Emacs
manual.

I’m not sure, as I don’t write that much C or C++ code. You can find
out easily what those particalar bindings are for your configuration.
Just press C-h k C-c C-c to check what the current binding is (there may
be none, which would be good). The same goes for C-h k C-;

I’m not sure if it’s canonical; just say something like this:
(add-hook
'c++-mode-hook
(lambda () (define-key c++-mode-map (kbd "C-c C-c") 'compile)))
I’m not entirely sure about which exact mode you’d like to use. I have
at least c-mode and c++-mode. You might have to repeat the above
expression for c-mode.

Oh, I'm aware of the bindings. What I meant was, I'm so used to
auctex bindings for compiling/commenting that I thought it would be a
good idea to use similar bindings for C/C++

Notice that M-; is the standard binding for commenting out code (and
various other comment operations). That should already work in all
major modes and should hence free C-c C-c and C-; in those modes where
they redundantly use it for commenting out code (those bindings
typically date back to Emacs≤20 where M-; was much more limited).
