In act 2, scene 2 in Romeo and Juliet, why is Juliet's soliloquy on the balcony unlike most sililoquies?

I always thought that Juliet's famous soliloquy is more about words than their actual relationship or her deepest thoughts. She muses about "a rose by any name smells as sweet". She questions "what's, in a name?" and of course what it means to be a Montague. There is little character development about Juliet herself or even Romeo. There is allot of metaphor and play with words and meaning. That's my take!
