I wasted hours on this, the root cause was stupid, and the solutions mentioned here didn't help (I tried them all), and the AWS s3 permissions docs didn't emphasize this point.

If you have Requester Pays setting ON, you cannot enable Anonymous access (either by bucket policy or ACL 'Everyone'). You can sure write the policies and ACL and apply them and even use the console to explicitly set a file to public, but a non signed url will still get a 403 access denied 100% of the time on that file, until you uncheck requester pays setting in the console for the entire bucket (properties tab when bucket is selected). Or, I assume, via some API REST call.

Unchecked Requester Pays and now anonymous access is working, with referrer restrictions, ect. In fairness, the AWS console does tell us:

While Requester Pays is enabled, anonymous access to this bucket is disabled.
