In my opinion and limited experience the highest velocity load you can shoot accurately through your pistol will be the most accurate.
Lower velocity loads may be accurate but the higher velocity load will be more accurate. If velocity gets too high then accuracy falls off, mostly, in my case, due to my marginal recoil management skills.
The high velocity / high accuracy load may not be the best for this sport. For me, the load that makes PF, has acceptable accuracy and is easy to shoot is my sweet spot.
Find a couple of loads your gun likes, set up a stage then see what the timer and score sheet say.
