Actually I would expect five wires for the sensors, typically they need both GND and a supply voltage. Long ago I took apart some old BLDCs and found some with passive sensors (some had pickup coils, others seemed to have two-terminal magnetic sensors, maybe magnetoresistive?). But I would never expect to find exotic stuff like that in a toy ESC like this...
I'd expect the red-white-black to be for the RC-servo like pwm signal to control the ESC

Five wires... oh yeah, of course.
After looking a bit further I found an e-bike controller that should do just what I want. There are heaps of these available at very low prices. I just want to mess around on the bench with a motor that is about the size of a coke can.

You're right, it does look just like a RC servo pwm cable. But that makes no sense on a BLDC controller (unless it's used to control speed, not position).

Well that does have five wires for the sensors, at least. e-bike/e-scooter controllers like those are probably a good option, so long as you have decent documentation for them.

plenty of bldc controllers with rc servo pwm interface for controlling speed
