Hello and Welcome!
At 5'3", I suggest you look at the seat height and handlebar style. Harley Davidson lists the seat height for each motorcycle on their website. You really have to sit on it to see. For example, my legs are 30" and my Fat Bob seat height is 26", so I can stand over the bike fine.
However, I realized that the stock seat was 29" away from the brake pedal, so to push the brake all the way down was almost 32", which was too far for me. So I got another seat that moved me closer. I found out the first time I rode on the freeway without a windshield and the wind pushed me all the way back on that original seat!
Also check to see that your arms are long enough to reach the handlebars in a tight turn. Harley has lots of handlebars and they sometimes can adjust the original ones to be closer to the rider. If you have your mind set on a particular bike, you could also lower the seat distance by changing the shocks but you don't want the tire to rub the fender if you put more weight on the bike. My local dealer has a "Fit corner" where you can mix & match seats & handlebars on a dummy bike.
Show us a picture when you get your Harley.
Good Luck!
