jexec(8) now supports -h hostname option to specify the jail where the command
will be executed.
Oh wow. That's all but current.
When was this added? I don't see it functioning:
3 years 6 months ago and it was shortly afterwards removed again as neither
a) the hostname not b) the ip addresses needed to be unique anymore with
multi-IP jails (a) not even before that). The suggested replacement was
-n to name the jails yourself. I think the uniqueness limit has since been
removed on that as well but the option has stayed and by default is the
jail ID these days and it's name=<..> in the modern syntax.

Bjoern A. Zeeb You have to have visions!
Stop bit received. Insert coin for new address family.
Yeah, seems problematic, from what I have seen so far everytime you stop
and restart the jail it gets a different jail ID, which would make it
difficult to cron anything to execute in the jail. I can't seem to get
jexec to take anything but jail id.
Came up with a temporary type solution assuming you have only 1 jail:
JAILID=`/usr/sbin/jls -n name|cut -d '=' -f 2`; /usr/sbin/jexec $JAILID
command
I can see this being problematic for a long term/portable solution.
