Qwant and Ecosia are especially notable for their efforts to build an independent search index.
For those who don’t know, most “independent” search engines, including DDG, still rely on Bing or Google results behind the scenes. They basically just act as a middleman by taking your query, forwarding it to one of those providers, and then returning the results to you. Some of them will attempt to reshuffle the order of those results to push the ones they think are best towards the top, but they’re still fundamentally limited to what Google and Bing choose to give them.
Presently a lot of Qwant and Ecosia searches go through Bing, but they’re collaborating to build an independent index which will allow them to become fully independent. I believe they’re already serving a mix of results from Bing and their own index, with plans to bias more and more towards their index as it matures.

I try to use my feed as a way to broaden my horizons by mixing in publications that are a bit outside of my usual wheelhouse. Normally what happens is I’ll randomly run across an article and, if I enjoy reading it, I’ll add the publisher’s feed for a while to see what else they have. For example, Smithsonian Magazine, Aeon, and Planetizen can all be interesting from time to time.
I would also recommend subscribing to at least one publication focused on your city or state/region to help stay informed on local news and issues. If you’re in the US you can try checking out the local member of States Newsroom.
And of course, make sure you get your regular dose of XKCD and SMBC
