Erik Demaine's DS class has a bunch of range trees and cascading method to speed up queries https://courses.csail.mit.edu/6.851/spring21/lectures/

His explanations are great and just wanted to +1 on the idea of range trees. Adding a reference here to a very lightweight read on range trees:

Thanks, I came across some of Erik's videos in my research but I didn't realize they were part of a bigger series focused on ranges. Cascading methods are exactly the kind of ideas I'm thinking about.
