I don't know very much but my son takes drum lessons at a local store that also has a recording studio. Last week, my husband decided to start taking guitar lessons at the same location. They worked with him to figure out the best instrument fit. The biggest information they gave was to look for strings that are close to the kneck of the guitar. The farther away the strings are the more effort it takes to play and the faster the player will fatigue. Since we were looking at acustic with ecetronic addins, I'm not sure if the same applies to bass guitars. I've found the people at the store to be good about not pushing the high end items but helping us to select instruments that have growth potential without being priced out of our budget.
Have fun
