The important thing with an ebike is not the type of motor nor the type of pedal sensor. It's the control system. The cpu in the controller reads the sensors (throttle, torque sensor, crank-speed sensor, brake sensor) and uses algorithms in the software to regulate the power to the motor.
Some controllers have bad algorithms, where the torque sensor is only used as a switch to switch the power on or off. Others have good algorithms that give the power just how you want it from either a throttle or a crank-speed sensor.
The right control system would completely transform the bike you tried with the 8Fun motor. The latest controllers from Kunteng have very nice algorithms that make basic hub-motors very pleasant to ride. There's virtually no latency from a pedal speed sensor, so you get instant on/off control with a realistic ramp to the current, which gives very good control of the power.
To summarise, you cannot judge all motors or systems by trying one sample. The controller is the most important component to give the control you want over your ebike, not the motor or crank sensor.
At only 71kg without significant hills, and wanting a speed of only 25km/h, any hub-motor system should be able to give you what you want.
I would recommend the 260 rpm 36v Q100H with this battery/controller kit from BMSBattery. BMSB have lots of other battery options that you could use with the S06S controller and S-LCD3

I guess there's lots of other kits available where you live
