I think (as has been mentioned) that having patience and allowing your internalization to happen over time is key. I do have a few suggestions:
Practice reading standard notation. The Simandl method book can be very helpful in teaching where the notes are on the fingerboard (while maybe not the most advanced fingerings for electric bass, it won’t hurt to learn them). Also, practice reading the melodies for standards out of fakebooks - start with the easy ones like Autumn Leaves, not Some Skunk Funk. When you can do that, try playing them up an octave. If you want to play jazz you’re going to need to know a bunch of standards anyway.
Practice playing all the notes - for example play every E up the fingerboard, starting with the low open E, then E on the D string, then the octave on the G string and then back down. Then do all the As, then Ds, and so on. Do it as slow as you need to and speed it up over time. Of course most notes can be played in multiple places on different strings, so take that into account as you progress.
Things like his don’t come all at once, and expect to continue learning for many years. For instance my teacher (I’m studying classical on upright, after a lifetime of playing jazz and rock) asked me a couple of months ago how I practice scales. I told her I do all the two octave major scales around the cycle of 4ths as a daily warmup. She said that was good, then asked me if I ever played them starting at the top and going down first, then back up. And I couldn’t do it! So I’ve been practicing my scales that way every day since, and it has made a huge difference in my facility up high on the neck.
best of luck, and enjoy the process!
