What are some current TV shows that are straight up acting clinics?

Now that my daughter is getting older i’m finally able to get some free time back and i’d really like to jump into an ongoing series. I’m looking for something like Succession (or even something like Glengarry Glen Ross in TV form) where it can just be the characters sitting in a room and talking for 45 minutes and you’re still on the edge of your seat because of the powerhouse performances and writing. Bonus points if it doesn’t have an extremely intricate and complicated plot to follow, I just want to see heavyweights chewing the scenery.
