I don't think short fingers are any big issue, just find a guitar that feels right. There are big differences in string spacing etc...some are wider spaced which is good for thicker fingers, and maybe you'll want something with a rather thin neck? You just have to test different necks to see what suits you well. Also shorter scale makes wider chords and extending the pinky a little easier. I'd try something like a gibson scale, maybe SG with a thin taper neck, see the difference between rounder radiuses and flatter Tokai copies etc. and compare those with a strat. PRS uses kind of a hybrid scale too.
