To get the ball rolling, here are mine:

Fiction: Three Body Problem by Cixin Liu — I’m late to the party, but this was an enjoyable read. I’m looking forward to reading the next two in the series.

Nonfiction: Designing Games by Tynan Sylvester — I’m not a game developer, but I thought the book was really thought provoking about designing products in general. Plus, I love Rim World.

Fiction Audiobook: Dungeon Crawler Carl by Matt Dinniman — I can’t recommend enough.

Nonfiction Audiobook: Careless People by Sarah Wynn-Williams — read by the author, a first hand account of the early days of Facebook, Zuck and Sandberg.
