The Guix equivalent is “guix pull && guix package -u”.

However, as you note, this is per-user here: it only upgrades packages
of the profile of the user that runs it.

This is a deliberate choice: we want users to be able to manage their
own package set by themselves.  Thus…

… upgrading packages of all users is not a central use case.  :-)

You *could* force each user’s ~/.config/guix/latest symlink to point to,
say, ~root/.config/guix/latest, and have a policy that only root runs
“guix pull”.  That way, all the users would be using the same Guix.

But users would still be able to bypass it, and that’s the whole point
of Guix anyway.

What do you mean by “system binaries”?  On GuixSD, system-wide binaries
(which are under /run/current-system/profile/) are upgraded by:

  # guix pull && guix system reconfigure config.scm
