Which should you choose?
The Cable Bench Press keeps constant tension on the muscle through the whole range of motion. The Dumbbell Fly works each side independently and demands more stabilizer control. If your gym has both options, neither is a wrong choice: pick the one that feels strongest through a full range, and swap after 6 to 8 weeks to keep the pectorals adapting.
