As for history podcast suggestions, there are many decent podcasts for specifics historical eras or events. Here's a few of my favourites:

https://thehistoryofrome.typepad.com/revolutions_podcast/
and old one but still an excellent:

I have more on my phone, but they're specific to UK history (where i live).
I've not listened to first two in a while as I'm listen to a lot of history books via audible. But I've listened to the first 100 episodes of the Byzantium podcast and the Russian Revolution episodes in the Revolutions Podcast - both are really well researched and produced.
If any one loves listening to things about the rise/decline of civs I can recommend the audio book version of Oswald Spenglers Decline of the West:

I plan to read the book version at some point but it's a bit of a tomb. So thought I'd approach it via the audio book first to get a better idea of the main concepts before reading it.
And i'm currently reading Arnold J. Toynbee - A Study of History, which is a fascinating look at the rise and fall of civs. It adds a different point of view to Spenglers theory and work.
Once you've exhausted all of his videos, though, I would recommend Mike Duncan's History of Rome, an equally compelling podcast that cover Rome's rise in 753 b.c.e. to it's "fall" in 476 c.e. [1]
