I just ordered a set of all 9 Rogue Squadron books; be interesting to see how the movie will compare. Other than that, I'm most excited for Bad Batch (since it looks to be a continuation of Clone Wars), Kenobi, and Acolyte. Super interested to see what a series focused on the old Sith in canon will look like, since the Old Republic is probably my favorite era of Star Wars. 

Slightly off topic, but is anyone else annoyed by what they've done to lightsabers in canon? I liked how they were just a highly customizable piece of technology, rather than the whole quasi-mystical route they've been taking with the sentient Kyber crystals and the whole Sith bleeding thing.
