This is all just a matter of opinion until we get more info on the exact mechanics. So my take on it is the Kinetic energy one. The fire is either just a manifistation of her aura like Ruby's rose petals are (thanks to who posted that, it really makes sense) or are a bit of waste energy from her semblance (or both). This doesn't make her invincible because using semblances consumes aura, so she'd run out of power eventually. Her biggest weakness would then be agile fighters who can keep wittling her down without taking any of her powered up hits in return. This kinda fits with Monty's comment about leg fighters. Yang is mostly a fist fighter so she doesn't know alot about leg fighters, can't predict them and thus they can avoid her while at the same time connecting with hits of their own.
