Anytime I want to listen to something and actually feel like I've gained some knowledge (*cough* when I'm not in the mood for true crime *cough*) I always go back to "[IN] pertinente" by Francisco Manuel dos Santos Foundation. What they do is basically a normal and very acessible conversation between 1 expert on a subject (Economy, Politics, Society and Science) and a "regular" person (a communicator from portuguese media). My favorite are the science episodes, but when it comes to Politics they have been touching on some really important matters (iykyk). If you speak portuguese, I would recommend you give it a try :)
