Half-relevant: I really like when dashes are used for dialogue. I think the way it's done in Spanish (and other languages that, alas, I cannot read) is especially stylish. See https://en.wikipedia.org/wiki/Quotation_mark#Quotation_dash
I've seen them used also as kind of a replacement for parentheses. Sometimes a phrase benefits from —but doesn't strictly require— an extra clarification.

Another thing to note is that if the quotation spans multiple paragraphs, you repeat the opening quote at the start of each paragraph (but not the closing one - it only appears at the end of the last paragraph).
