Ruby doesn't need to learn anything specific. She can well do the same as Yang and just use an improvised style that doesn't fall into anything specific.

For Yang this works because her Semblance means all she needs is to land a punch/kick. For Ruby it would work for a similar reason: Her Semblance is Speed. And thanks to Newton, if something has enough speed, then it will have a lot of force behind it when it hits something.

All Ruby needs to do is learn how to use her Semblance better. Then she can just do what The Flash does: Go fast. By moving fast, her oponents would have a hard time defending themselves or avoiding the hit, and at the same time, F=m.a means that her hits will be very strong, while Aura shields her from the resulting reaction, same way that it protects her from her shots's recoil.

.....In fact, that's exactly what she used to do with her Semblance and Scythe back when the show was cool. Use her Semblance to go fast to make her slices much stronger and gain Momentum. All she needs to do is, well, do the exact same thing.
