I think most communists would agree that libraries are a good resource.
As a side note, there can also be libraries of things other than books and media, like toy libraries (so parents aren't pressured to buy tons of toys but kids can still borrow and play with different toys), tool libraries (so people in a community don't have to all individually buy tools that they might only use occasionally), home appliance libraries, electronics, musical instruments, etc.
These services are more marginal under capitalism because they're not for profit. Under capitalism, big libraries of items which can easily be borrowed for free is not a welcome idea for capitalists seeking to profit of off false scarcity of their products, and its harder to maintain non profit services like this. In a communist society, there wouldn't really be a reason to hinder the expansion and enhancement of libraries to make them even better resources for the public.
This list will include some non-ML and some non-socialist content, as you said you are just trying to expand your basic knowledge and don't mind some liberal content, so I am trying to give a wide list so you have various introductory jumping off points.
I recall this video on Chile being a decent overview, someone please correct me if they know of issues with it - I don't know anything about this channel besides this video.
Geopolitical Economy Report on Chile: The first 9/11: How the CIA overthrew Chile's democracy (and pillaged its copper)
CGTN Africa has a documentary series called Faces of Africa, which covers many famous African leaders, serves as a very basic introduction
Geopolitical Economy Report (in addition to his news coverage/commentary, you may be interested in his series of interviews with Aaron Good on the history of the US empire; episodes are connected somewhat by their historical timeline, but can be easily watched standalone by topic).
Blowback (history podcast, covers: Iraq (s1), Cuba (s2), Korea (s3), Afghanistan (s4) Cambodia (s5) and focuses on the confrontation with imperialism)
Empire Files (this interview with the author of the Jakarta Method could serve as an overview of historical topics you may want to look more into as you learn more)
John Pilger documentaries are decent introductory material on various conflicts and issues around the world (most of his work was made from the 80s to early 2000s iirc)
Documentary: The Future Coming Towards Us (about Grenada)
Documentary: The Weight of Chains (about Yugoslavia)
