I admit this is also what I did, i.e., hitting ' ' for all labels and
not 'l', but you're right. In theory, it should be enough to do this in
your init file:
--8<---------------cut here---------------start------------->8---
(setq reftex-label-alist
'(("\\lstinputlisting[]{}" ?l "lst:" "~\\ref{%s}" 2
(regexp "[Ll]isting"))))
--8<---------------cut here---------------end--------------->8---
But I couldn't get it working, can't tell why.

You're welcome.

Yes, this is unfortunate, but I don't have a solution right now.

It seems you don't plug RefTeX into AUCTeX.

Ok, thanks.

Delete the last form and try something like this:
(use-package reftex
:hook
((LaTeX-mode Texinfo-mode) . turn-on-reftex)
:custom
(reftex-plug-into-AUCTeX t))
This should activate RefTeX properly inside AUCTeX.

See above.
