macOS switched to launchd from inetd a very long time ago. If you're going to use
macOS as a UUCP node you'll want to enable the com.apple.uucp service, which will
ensure uucico is run for you by the system.
I noticed that the following files weren't set UID
or GID like they are on Linux. But I don't know if that's a macOS and / or *BSD
difference when compared to Linux.
/usr/bin/uucp
/usr/bin/uuname
/usr/bin/uustat
/usr/bin/uux
/usr/sbin/uucico
/usr/sbin/uuxqt
Adding the set UID & GID bits allowed things to mostly work.
That's a macOS difference, not a BSD one. I don't *think* you need to re-add any
setuid or setgid bits, but I could be mistaken. It's been a very long time since
I've actually used UUCP. If they do need to be made setuid or setgid, that sounds like
a bug.
Aside: Getting the contemporary macOS so that I could
edit the (/usr/share/uucp/) sys & port files was a treat.
In macOS 10.14-10.15 these files are indeed covered by system integrity protection, I
think that's probably a bug since they need to be edited by a sysadmin to use UUCP.

PS - Here's the UUCP source for recent macOS:
