I try to avoid fic demonizing women and promoting damaging sexist stereotypes.
I try to avoid fic pushing narrow concepts of ideal womanhood (and am grateful to those authors tagging theirs with "ladies being awesome").
I try to avoid fic reducing female characters to objects to be conquered or won.
So that does make it a bit difficult to find het fic for the ships I like. Mostly I stick to enjoying canon, and making up my own stories. Sometimes an author I trust will write het (slashers tend to be relatively good with avoiding stereotyped gender dynamics), and sometimes I'm lucky and randomly come across a het fic I love:
"An Algorithm for Mistakes" by fleete is great. It's strongly grounded in canon characterization and makes reference to events and mythology from the show, but it's long and meaty enough a character-driven story that I think it can be read and enjoyed by those only familiar with Teen Wolf by fannish osmosis.
Lydia in this fic is not a lady being awesome, she is a BAMF. She's flawed (real person flaws which impact the plot, not Hollywood flaws making her quirky but cute), she has a mysterious traumatic back story and super math skills (not the man pain and super strength and healing of Derek, but still that over the top deliciousness I prefer in my hero fic), and yes, she is a hero: she overcomes the obstacles, she owns up to and fixes mistakes, she grows as a person even when it is painful, she wins the pretty boy, and she does it all while being smart and funny and mean and fashion-self-conscious.An Algorithm for Mistakes

Lydia has a plan: attend college, study the biological makeup of werewolves, win prizes, and wear amazing shoes. She does not expect to make friends with Stiles. Or flirt with Stiles. Or accidentally start a pack war with Stiles. Whatever. The point is, Lydia has a plan.
