The trick is to have an idea yourself - What YOU want in a character. Even write a little story of that charater first and their bringing which shaped them until 16 or so.

maybe she fights to avenge her murdered family, or out of naive boredom or because she had to survive on the streets all her life... Maybe she finds heavy armour and large swords too big and unwieldy for her so she prefers the light armour and short swords. Maybe she don`t like fighting face-to-face so decides to go for the archer approach.
Or maybe her Nord dad wanted a son and sort of adopted his daughter like a boy making her want to fight with two-handed claymore and even trained her to withstand war and punishing tasks to toughen her, so she`s like a barbarian of a sword wielding woman. ETc, etc...
But it`s your character and you must ultimately decide since you`re the one stuck with it for hours.
