Working on my first AR pistol. I already have a complete lower receiver so far, but trying to decide on upper length and brace. Looking for any suggestions.

I definitely suggest putting an upper on it, if it's a pistol, I also suggest a brace.  If I knew what you wanted to do with it, then I might be able to suggest more.

Here are a 12.5, 11.5 and 10.5.
The top is a TNT upper, the middle is an Aero, and the bottom is an inexpensive PSA kit

First, welcome to AR15.com.  But, how can we give you meaningful suggestions without knowing your goals?  Will this be used for personal defense, hunting, target shooting, plinking?  Is ammo cost a consideration?  Assuming that the lower is standard AR-15 you are kinda limited to 5.56 length calibers - 5.56, .300 Blackout, .350 Legend, etc. Or is the lower designed for pistol calibers?  Please give us enough information to actually help you make an informed decision.
