In the few short hours since I started using #Threads, #DuckDuckGo has already blocked over 200 data tracking attempts. These include things like "headphone status" and "screen density."

Companies like Google and Facebook don't sell data. That's a common misconception. Having data that other companies don't have is what makes the companies valuable, so it doesn't make business sense to sell it. What they do is allow advertisers to target people using that data. Advertisers never actually see the data, nor the exact users their ad reached, just aggregate metrics.
Don't they have partnership agreements and secondary products that repackages their data as insights? (I'm thinking Cambridge Analytica.) It's not a direct sale, per se.
Repackaged data in the form of other products is one way to do it.
No. Cambridge Analytica scraped data via the Graph API, which was open for apps to use.
The original idea with the API was that apps could become more social - for example, Spotify had a Facebook integration that'd show which of your friends use Spotify, and their favourite playlists (if they chose to share them). To handle this, the API granted access to not only your data, but some of your friends data. Keep in mind, this was all public profile data that people chose to make visible to public or at least to their friends.
That was fine when people were legitimately using it, but there were bad apps that didn't follow the rules. Cambridge Analytica scraped data via a quiz app. People would click a link and log in to a quiz app on Facebook. The log in page shows a list of the data types that'd be shared, but people still logged into it. They'd then scrape all accessible data for both the person that logged in, as well as the data their friends had shared.
The API is very locked down now. People that use the API have to have a privacy audit of some sort, and much less data is available. A lot of people don't like the API being so locked down (for example, it's impossible to make third-party Facebook apps), but there really wasn't any other choice.
Thanks for taking the time to educate me (and any passing readers.)
