Look around in your online communities and see what publications get shared.
Once you find some sites you like, search the web/communities for alternatives with the same topic/vibe.
If you find journalists you like, see where else they publish their works, or what publications they used to work at. For bloggers / content creators, see who they collaborate with.
Most of the feeds I subscribe to came to me in one of two ways:
I enjoyed reading an article posted somewhere else (Lemmy, etc.) so I sought out the feed of that publisher.
Sometimes news outlets enter into agreements to republish each others articles. When they do this, the re-publisher will usually include a little blurb at the end giving credit to the original publisher. If a feed I’m already subscribed to has an article re-published from elsewhere then I click through and check out the original source to see if I want to follow them as well.
Wordpress sites publish an rss feed by default at site.com/rss or site.com/feed, so there’s a good chance a site you want an rss feed for has one even if they didn’t intend to.
How do you all discover new RSS feeds to subscribe to?
I use Feedly for discovery, they have a crap load of websites you can subscribe to even if the websites don’t explicitly advertise RSS.
And then use the Feedly desktop website to get the actual RSS URL and put it in the client of your choice 🙃
My way is simple and stupid. I hit F12, then search for “rss” in the html and copy the link

After spending lots of time trying to find feeds, learning this was super helpful
I use an Browser Addon that searches for RSS feeds, still a bit finiky sometimes but still better than manually guessing URLs
Kagi Small Web, personally. Also a lot of people who blog on the Fediverse have RSS feeds, so discovery via Mastodon and such is good too.
I use an extension that searches the code on the page to find them. It puts a little number up, then when you click it you can copy the link.
