Thanks for the reply, I ended up solving my particular problem by
spinning up a python script shepherd service that monitors elogind for
shutdown and sleep events via D-Bus.

I've seen other people solve the same problem by creating a dummy
"sleep infinity" shepherd service, and then adding the code they want
to run on shutdown in the service's destructor (but this doesn't handle
sleep). Like this:
