Using https://www.spf-record.com/ I have checked my SPF records which are reported as 'SPF check passed'. My DKIM also passes various test suites. Yet, Google is still rejecting mailman messages to any and all gmail users. I have even filled out their short form for delisting at https://support.google.com/mail/contact/bulk_send_new all to no avail. Example of block logfile message:

Could the hard fail policy be implicated in the gmail rejection?
Other than readdressing my server, is there anything else I can do?

You can only have 1 SPF record.
For a domain. But as Jeremy Stanley noted, mail.ccalternatives.org and lists.ccalternatives.org are different domains and it is fine for each to have its own spf record.
