Well, every subreddit is an RSS feed (ex: http://reddit.com/r/artificial/.rss) so if you have a favorite sub or two, you can follow those in an RSS reader.
This is cool and fun because you can use Bluesky as RSS PubSub infra. You simply post as a user and clients can consume via RSS, you rely on Bluesky's PDS or host your own, etc.

Likewise, there is the HN RSS feed: http://news.ycombinator.com/bigrss
Also, all arXiv categories have RSS feeds associated with them: https://rss.arxiv.org/rss/cs
and you can also do individual subject classes within a topic:
https://rss.arxiv.org/rss/cs.LG
But of course if you're asking about my favorite feeds, I guess I'd have to say "my own". :-)

Also, all Mastodon users' posts appear in their RSS feed.
My most reliable way to find feeds is to read things here. Then if I like the article I subscribe to the blog.
Arguably the #Junited2005 thing this month has been about finding good blogs etc; most seem to have RSS.
