I am looking for a way that you, or anyone else, could indicate a domain

You might be able to use lack of an SOA record as a hint.  In my
experience, parked domains often do not have SOA records because
the parking companies are lazy.  It is a lot easier to put all the
parked domains in a parent zone file, or even use a wildcard, rather
than have a zone file for each parked name.

Surely for that to work for most of the domains we're talking about, the parking companies would need to be able to insert arbitrary records into zones such as "ORG", "NET" and "COM", which isn't something that any of the registries for those zones permit.

Do you have an example of a parked domain with no SOA record?
