1-3-2-4 fingering exercises all the way up the fretboard, and 4-2-3-1 fingering exercises all the way down, and vice versa are really helping me train my fingers to work more efficiently across the fretboard.
I've been doing this in octaves and on single strings...and the octave version when said aloud with the notes has really helped me learn where the notes are too.
Add a metronome to the mix and I'm working on my fingering, note recognition, and time - all at once
