Lots of different things at different times. There's a guy named Dennis Sandole who wrote a book called Guitar Lore
Guitar Lore: Dennis Sandole: 9781598060874: Amazon.com: Books It's an amazing set of everything from chromatics, open strings, chords, scales, etc. He was a teacher for Pat Martino and John Coltrane among others. You get why when you look through this stuff.
I run a bunch of exercises from Jazz Guitar Technique by Andrew Green sometimes. That gets me playing shapes, lines and fingerings I'd never have thought of. It really opens up the guitar for me when I've been consistent with it for a while.
The thing I come back to the most is from my old teacher, Mike Elliott (monster jazzer and studio guy). He was a student and music store co-owner with the legendary Johnny Smith. Also rep'd for Gibson and did tons of duets with Howard Roberts. Friends with Pat Martino and lots of the other jazz guitar monsters. He got an exercise from Johnny Smith that was his technical thing every day when he practiced. It's 3 octave arpeggios, major, then relative minor with specific fingerings through all 12 keys, then the same thing for major, then harmonic minor scales. HUGE emphasis on doing it cleanly, evenly and with every note well articulated. If not, slow down. He'd say minimum pro level execution was Arps at 120 and scales at 132. He could get them up over 180 on a jazz box with at least a 15 on his high E, but then he broke a tendon in his picking hand. The last time I heard him play before his health went on a total down slide he said he'd gotten up to something like 158. He was completely dancing on the jazz tunes he played. It was some of the most amazing shit I'd ever heard and the freedom of execution was startling and always musical.
I don't often use the fingerings of the 3 octave stuff I practice when playing, but doing that stuff has totally freed up the fingerboard and I find myself comfortable all over the place.
On the slow side of things which I almost never hear anyone talk about when they talk about practice, I practice a lot of chord melody stuff which strengthens me hugely and is actually playing music as practice.
