The endings are
Make remote CUPS printers available locally
and
Network Time Synchronization
I've checked for CUPS and NTP errors in the logs and have found nothing.
I presume that's because this happens during shutdown, but haven't done
enough research to be sure.
I would try the following as next steps.
Before shutting down, start the debug shell on tty9
# systemctl start debug-shell.service
Okay, this didn't go as I expected. When I tried to switch to tty9 I got
a blank screen with a flashing underline cursor in the upper left corner.
I don't remember ever having looked at tty8 or tty9 before.
I tried to follow your directions as closely as possible by issuing the
above command from the root account on tty6.
After I switched back to the GUI on tty7 and initiated the shutdown I
was able to switch to tty9 where I was greeted by a root prompt from
which I issued the commands below.
Then on shutdown switch to tty9 and save the output of
ps aux

and maybe attach an strace to the process(es) which don't want to die.
I'm going to have to do a little reading on this utility to figure out
how to use it.
Is there any particlar set of commands and / or options I should use
with it to get the results you feel might be useful? I gather that I
open a terminal emulator or use a tty, log in as root, get the PIDs of
the recalcitrant processes, and attach an strace (set to record its
output to a file) to each of them, then initiate the shutdown?
Sorry that I'm not used to doing stuff like this, but I'm willing to
give it a try if it can be helpful.
Thanks for your help, Michael. I'm a fan of your work.
