Matched with the right shaft for a golfer, the distance between a 300 cc head at 43.5" and a 460 cc head at 45.5" is about 10-15 yards. Disbursement pattern will be purely up to the individual.
I was surprised at my modern day weapon was not a lot further than the persimmon driver from almost 4 decades ago. Yes it's about 10-12 yards longer but I thought it would be a lot more.
The major difference for me came from the fairway woods, the modern day 3 wood is much easier to hit off the turf and longer by at least 15 yards.
The length of the driver should be focused on the ability of the golfer to deliver the driver head to the golf ball.
Some will not find much more accuracy using a shorter driver than a longer one, some will find easier to find the sweet spot with the shorter stick. Some will find no major difference.
There is no one formula to every golfer. Some have the image of themselves not able to hit a driver with longer shaft, but they had never tried a longer shaft with the correct match.
I was cast in the mode of stiff flex everything, and 1/4" shorter length ( irons ) with 2 degree flat lie when I was younger. I did not have the opportunity to discover what really fits my game until I was over 45 years old that I could swing an X flex in driver and perhaps with the irons.
It was a joy to discover the upper limit of my game, came a bit too late but nice to know half the struggle I had had in the past with this game was equipment related.
