You probably want "display-manager.service" instead of
"graphical.target".

You also will want "Requires=autofs.service". The distinction between
"After/Before" and "Requires" is exactly for the reason you give; the
ordering directives don't require anything, so without
display-manager.service enabled, Before=display-manager.service is just
a no-op. Actually, you might even want "BindsTo=autofs.service", which
is stronger.

Depending on your setup, you many want to look at converting your
automatic mounts into systemd mounts, and depend on that directly,
rather than on the autofs service.
