You can achieve ClearURLs directly in uBlock Origin.

Can also add lists to your filters to assist. “Actually Legitimate URL Shortener Tool” and “ClearURLs for uBo” are the ones I am aware of.

Check the global app settings. Under Network you can limit your total downloads (Automatic Downloads). For example, I have it limited to 10 downloaded at a time. See if that helps you out.

You can literally accomplish your use case with AntennaPod. You clearly have some issue with FOSS though.
