I'm guessing the expected usage is to write a shepherd service.
Looks to me like almost everyone using Guix uses shepherd / mcron, not systemd. 
I hacked something together for systemd, but haven't published it.

Also, it looks like you're not using Guix home, which I think is the best way 
to use Guix on a foreign distro.
So I suggest looking into that: 
https://guix.gnu.org/manual/en/html_node/Home-Configuration.html

Yes. In ~/.config/systemd/user.conf (file probably doesn't exist yet):

[Manager]
ManagerEnvironment="XDG_DATA_DIRS=%h/.guix-profile/lib"

In case the %h doesn't work for you (depends on systemd version), write 
/home/rodrigo (or whatever) instead.
After restarting the user session, it should pick up the unit files.

You can check the paths that are checked for user unit files with:
systemctl --user show -p UnitPath --value

and of course, the following:
systemctl --user list-unit-files "thunar*"

Just making sure, but are you sure you want to start, and not enable, or enable 
--now?
