Moving offline is the best one I have. Talks about digital minimalism quality feed. Nerd fitness one is pretty cool too. The rest that I have are very location specific.

I'd be curious to hear which ones you follow as well. Always looking for new feeds

Hackaday is great if your a maker!

Not quite "useful information", but I use RSS for entertainment that isn't social media algorithm or meme based stuff. Webcomics are so great to have in RSS feeds. My favourites are:

Last place comics

War and peas

Mr Lovenstein

Poorly drawn lines

Oglaf

The Perry Bible Fellowship is a great comic

pluralistic.net is Cory Doctorow's dailyish blog with neat links or reads
