Aura is the 'power source', but semblance is unique to the person in how it's used. For jaune, he understands it as a force field, so it'll likely manifest that way (Now's a good time to look at his emblem). it's more or less how the individual's willpower manifests.

Weiss's Semblance are the glyphs, but as for her archetype, she's 'white' as in 'prismatic', possessing all colors (a fair match for a rich-bitch). Of all the 'fairy tale' girls in RWBY, she's the only one whos allusion started as an actual princess.

Ruby, like Yang, aren't disney princesses, but share a common theme in dealing with beasts (Wolves and Bears, respectively). Yang, like Goldilocks, plays off well as a shameless intruder, while Ruby is played off as innocent (but it's yet to be seen how easily she can be decieved).

In general, there doesn't appear to be a correlation between Semblance and their character allusions nearly as much as it simply compliments their combat styles, with Weiss being a particular exception.
