jazz guitar requires a narrower neck since it relies on fast chord changes.
There are so many electrics to choose from, surely one works for short fingers.

Acoustic guitars present a different problem. You don't need a lot of chord shapes but the coordination of right and left hand for picking is important.

The classical guitar approach can work for basic accompaniments to many folk songs such as Dyer-Bennet and his Ray de la Torre (teacher guitarist) approach but is limited to a classical genre re interpreting folk songs. (John Henry by Dyer-Bennet is a case in point).

I found the Martin 0021 to be a compromise between the neck sizes but some work has to be done on slimming the back of the neck down without compromising the integrity of the neck. John Carruthers, (L.A. luthier) did this for me effectively and I haven't changed anything much since he set up the action on the guitar and shaved the back of the neck down.

The width of the neck from fingerboard to back of the neck is important here.
