I'm using the following line:
$ su -c "systemctl --no-block reboot" && exit

I enter my password, then I instantly see the broadcast message telling
me that the system is going down and the ssh session gets closed.

If you started the session as root, this line should do:
# systemctl --no-block reboot && exit
I didn't try it, because root login is disabled on my machines.

Regards,
Robert.
