Just tried this and run0 nixos-rebuild switch seems to work now for me by and large. The only extra error I get is:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LANGUAGE = (unset),
        LC_ALL = (unset),
        LANG = "en_GB.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

Other than that it seems to work as expected.

But with plain pkexec all fine.
