If you use "su" this creates a new login session (and thus a scope
unit) for your program, and thus any processes/logs will be associated
with that login session scope unit, and not with the service unit you
are writing here.

Use "User=" to run services under specific user identities. Or at
least use "setpriv" rather than "su" since the former just changes
privs, but doesn't actually acquire a PAM session and everything.
