I'm assuming that the results you report here correspond to the unexpected
UPS shutdown on a re-booting Ubuntu box.

I do not see any delayed UPS shutdown messages. How do you call for a UPS
shutdown?
# So the system does poweroff. RPi is using SSD
# After this the UPS resets ...
# Command used to perform reboot.

shutdown -r now
reboot

I do not see any command to stop nut-server. Did you stop NUT before rebooting
as suggested?
This is aside from your unwanted UPS shutdown problem. I do not understand why
you call "reboot" when you have already asked "shutdown" to reboot.
# Following services are started by systemd at boot:

root@fourpi01:~# systemctl list-units | grep nut
nut-driver.service
loaded active running Network UPS Tools - power device driver
controller
nut-server.service
loaded active running Network UPS Tools - power devices information

--snip--
I would expect to see
nut-driver.service loaded active running Network UPS Tools - power device
driver controller
nut-monitor.service loaded active running Network UPS Tools - power device
monitor and shutdown controller
nut-server.service loaded active running Network UPS Tools - power
devices information server
What happened to upsmon?
