I really enjoyed the The Bit Player (2018) about Claude Shannon, it uses an actor to play Shannon.

I thought More Than Robots (2022) seemed really cool too, about teams of teenagers building robots for a competition.

https://www.youtube.com/watch?v=EsIo57pH-pA - is an interesting short documentary on the making of neon signs.

Birdmen: The Original Dream of Human Flight (2012) was pretty fascinating on the history of wingsuit flying

And also Jiro Dreams of Sushi.
