Best way to set up a podcast RSS feed (how to filter, etc?

Hi, trying to get my RSS feed working outside Cloudflare, but I can’t figure out how to do this. I figure this would make a better help document than a discussion with yours truly, but this is where I am right now.

These are my page rules. I’ve purged the cache already. How do I ensure my RSS feeds are not cached? It’s been the same wrong cache since September 15, which means Apple/Spotify cannot process any of my new episodes.

Are there best practices for this process? Any recommendations?
