I want the drone with best camera!
There the Autel EVO II. It has an 8K camera. I don’t think you can easily put ArduPilot on it.
Of course you can add an 8K camera to any drone capable of lifting it. I’m sure there are lots of 8K cameras flying around. I think NURK FPV has a couple videos talking about setting up a drone to fly 8K cameras.
I would say the Autel EVO II, 8k Camera drone, but it has been discontinued. I would recommend the EVO II Pro V3 Camera drone, which is a 6k one-inch camera drone.
