I've managed to come across a few good examples of A/B/O femslash:
Animals and Prizes (Tori/Jade, Victorious fandom) - In addition to being well writtem, this fic also uses the Alpha/Omega dynamic to look at some of the more sexist tropes, and how the characters work their self definitions around the facts of their biology.
Portions of Happiness (Molly/various, Sherlock) - Embraces the paradigm of sexuality being governed by your A/B/O-ness, rather than whether you are male or female, and explores what queerness might look like in that world. (With queer ladies, natch)

A Fine Job of Bending All the Rules (Genevieve/Adrianne, Supernatural RPF University AU) - A genuinely fun little series
