Do you recommend creating a cleanup rule (last rule to deny any any) in PA? As far as I know, PA firewalls only allow traffic explicitly defined, and the last DENY is a built in "known rule"…correct?
or will the interzone policy take care of this?

The Interzone default acts as a "cleanup" rule for traffic between zones. You should still set logging on it to capture that traffic in logs.
The intrazone rule is for traffic between the same zone and is a default ALLOW. So inside-inside or outside-outside.
Generally, a cleanup rule isn't required, but as with all things, there is likely a use case out there.

The whole thinking of having a "Clean Up" rule usually is for testing or for logging.
There may be other ways you can gather the same information,, but that is why you would want to have one.
