So it would seem that the pipewire client cannot connect to the server
(or something like that). Could be ownership, permissions, even selinux
if it is running.
It could also be that running things from cron does not establish a
"session" and then you do not have access permission to audio devices
and such (and dbus, as suggested elsewhere in the thread).

Try:
/usr/bin/pw-record /home/john/crontest.wav > /tmp/cronjob.txt 2>&1
...and have a look in /tmp/cronjob.txt after it's run
/tmp/cronjob.txt says error: pw_context_connect() failed: Host is down
I've no idea what that means, or why that should be so. I tried with arecord in place of /usr/bin/pw-record
and got:
arecord: main:852: audio open error: Host is down.
