As for why Ctrl+Z suspend doesn't work, perhaps poudriere-3.3.6/src/poudriere-sh/helpers.c is trapping it.
However, it does trap SIGTSTP, but not SIGSTOP.
In other words, Ctrl+Z with SIGTSTP will not suspend, but SIGSTOP will.
I actually used the following method to suspend it.

# Find the jail
jls -v
(snip)
    87  foojail-default-job-01            /usr/local/poudriere/data/.m/foojail-default/01
        foojail-default-job-01            ACTIVE
        5
        127.0.0.1
        ::1

# suspend all processes.
pkill -STOP -j 87 -a
# restart the process
pkill -CONT -j 87 -a
# note: this will not suspend
pkill -TSTP -j 87 -a
