I can’t recommend a guitar for you because I am not all that familiar but I do know not all guitar necks are the same width. My classical Ephiphone is much wider than my Martin or my Taylor GS Mini. If you look on line at a guitars specs it usually says the neck width and length.

As you play and stretch you will find your hand becomes more flexible. It takes a while but it happens. And it is not uncommon for your 5th string to get a little muted in a G Chord. Try the full 4 finger G and it happens less.
