wrt conf file location, they’re only generally in /usr/lib/systemd, /etc/systemd, or /run/systemd. You can always find out what’s getting read with systemctl cat <service-name>. Way easier to find stuff than with some other random programs imo, I’ve seen crap have default conf files in dumb places like /usr/share/<service-name>/lib/etc.
