In terms of dramas you may find In the Name of the People interesting.
For documentaries, I've recently seen mentions of How Yukong Moved the Mountains, although I haven't yet found a place to watch it.
There's also a large collection of leftist movies which includes fictional dramas and documentaries about USSR and PRC over on hexbear. https://hexbear.net/post/9615
Edit: CGTN also has some good documentaries on modern and historical events.
A good documentary, on the USSR though not modern Russia, is The Human Face of Russia. You can find it on YouTube. It's Australian as well so it's interesting seeing a look into the Soviet Union from the point of view of a country that is aligned with the US but without so much Red Scare propaganda.
