Westnest,

FBW vs Cables and pulleys makes no difference to the yoke feel it's exactly the same, both are completely artificial. Under the floor is a mechanical set up just the same as any Boeing yoke which at some point connects to springs to provide artificially feel and some additional hydraulic/electromechanical resistance when required.

The trick with FBW is to make sure the 1cm, 1 inch or whatever amount of movement under the floor translates to the corresponding hydraulic actuator movement and resulting flight control movement and pitch/roll rate plus provide the visual yoke movement feedback.

As stated FBW can take advantage of the fact that the lack of mechanical connections between yoke and actuators means the flight controls can be commanded to move without having to feedback to the yoke and therefore remove the requirement to trim as it's being done behind the scenes with no feedback.
