anyway it is easy to change the stylesheet to suit your tastes. and current versions of calibre can remove all the extra css crap via an epub to epub conversion
We set almost all our books to left-justified, for the simple reason that then the user reading the book can choose what s/he wants. If, on the other hand, you set it to full-justification, most reading devices can't/won't override that. I'd rather give readers the choice than not.
We use the xpgt in some books, depending upon what is required. The only "absolute" in ebook-making should be that there should be no absolutes.
