Yipes...lineric you really do not need 650c wheels nor 165mm cranks.
A 48cm C'dale frame will do you just fine with standard wheels and a 170 crank.
C'dale frames are a touch larger center to top than most frames of the same size.
You will have reasonable stand over height...it will never be what a taller person has with a correct fitting frame but it is what it is when we are 5'5" there is never a lot of stand over height lol.
I think you will find it a much better fit and more efficient and comfortable compared to what you have been riding.
Have the bike set up...seat back, proper stem length, rise, etc. and enjoy.
Keep us informed.
