I do not daily use emacs-guix so I do not know.

…and maybe emacs-guix is doing this under-the-hood which would be really
nice; other said, check the substitute avaibility using the data
provided by an equivalent of “guix weather” and if the substitute is
available, install it.

But it would be more complicated, because you would like to know if all
the dependencies you need are substituable; which is, AFAIK, not
straightforward to know beforehand.
