On top of the ones already mentioned, if you’re a hardcore history fan than I highly recommend The Martyrmade Made podcast. Same style as Carlin in that the host spends 35+ hours on a select topic (Israel-Palestine conflict, Jim Jones and corresponding social/political environment, human sacrifice, etc) and you come out of it genuinely feeling like you learned about a topic beyond the first layer. The length of the podcast allows the host to dive deep into relevant rabbit holes which makes for a very interesting and well-researched listen.
