I found these lectures by Leonard Susskind very insightful:

- Leonard Susskind on The World As Hologram (https://www.youtube.com/watch?v=2DIl3Hfh9t)

- Leonard Susskind | "ER = EPR" or "What's Behind the Horizons of Black Holes?" (https://www.youtube.com/watch?v=OBPpRqxY8Uw)

- Entanglement and Complexity: Gravity and Quantum Mechanics (https://www.youtube.com/watch?v=9crggox5rbc)

As a note to the poster: The first video is not available where I live (Netherlands), maybe the link is wrong, the others are however.

Just adding: it is unavailable for me here in India too.

This one works for me (UK):

I would also recommend (8 lectures)

Despite the name this is largely about general relativity and black holes and other horizons. The best detailed description of black holes for laymen (assuming you have algebra and basic calculus) I've ever seen.

To add to those

The Perimeter Institute ones

The Royal Institution ones

There's multiple of each devoted to cosmology and black holes in particular.
