AKG 451 and Rode NT1 (not NT1A) close to each other over the soundhole, diaphragms in line with each other and pointing slight outwards towards body and neck. Careful that it's not too boomy, so listen before you start recording and move the mics back if need be. Line out for low-end (low-pass filter applied) in case it's needed.
Pan the two mics hard left and right.
Get the player to play in the booth while YOU wear the headphones and move each mic around to decide on position.
Or one mic and one DI left and right.
Or another fun way is to mic from the top "Player's perspective).
Or you can also do all of the above and two distant room mics and blend them all in to taste, but rather track them to separate tracks for safety as sometime that great idea just sucks the next day :O)
NO matter how good an internal pickup system is, normally a decent mic will be better..
And NEVER underestimate how much a nice chunk of compression can help an acoustic guitar mix..
Others may, of course, disagree with all of the above!
