Guitarist seeking advice

Hello! I'm a long time guitarist, I'd say intermediate, can tap and am fairly good at odd times from my love of prog music, however, as someone more heavily into Jazz and fusion these days, I notice the gap i have is being stuck in that box of the blues pentatonic, even if i can go from major to minor and all that jazz. Can anyone recommend me some good exercises or scales or something to focus on that will break me out of that box?
