iirc ZR/ZL activate the flurry punch, while R jumps (I can't remember whether R and L do the same thing or not) - I can see why you'd want them switched round though, seeing as how you'll be jumping far more than you'll be doing a flurry.
With the motion controls, the majority of your actions are mapped to the motion sensors rather than buttons. From what I remember:
- Flick joycon to punch
- Flick joycon in a curved motion to do a hook punch
- Hold joycons horizontally rather than vertically to block
- Lean left, right, forwards or backwards to move in that direction
- Thrust both joycons forward to grab
I can't remember how you do a quick dash
