Who are we?
We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
We are one. We are legion. And we're trying really hard not to forget.

Audiobookshelf selfhosted with docker is an excellent option I use.
I started to archive podcasts like Small Town Murder and Crime in Sports, but also downloading stuff from the BBC, I really like their audio dramas. I'll probably expand to other podcasts once I find more good ones.
If self hosting is your thing I use audiobookshelf to download the podcasts I subscribe too, has a nice interface to navigate them, and even mobile apps.
Not quite what you're looking for (public archive) but a good starting point for a personal archive
That’s almost exactly what I’m looking for! Do you use their mobile apps to listen to podcasts? I didn’t see anywhere in their docs about exposing RSS feeds for podcasts to allow usage of existing podcasts apps.
Might just make my own to achieve that, I essentially just want a man in the middle archive of all the podcasts I am subscribed to so I can continue to use my existing podcast clients
I do use their app but I'm pretty sure you can have your own RSS for audiobooks, and I'm assuming for podcasts too. I really recommend you give it a go :) let me know if you need any help, or just at the selfhosted community. Happy to help
Edit: just checked, yes you can have your own RSS with audiobookshelf, so you can still serve to your favorite podcast app.
