I don’t have any written suggestions, but you might want to look into philosophy material. I like the “Philosophize This” podcast (30 minute episodes).

He starts out chronically, but somewhere between episodes 100-150, he moves to topic or school of thought. It’s quite rough in the beginning and I think he states that new listeners should just skip to episode 120 or something (on episode 219 now).
