Short, Strong, Medieval/Arthurian Girl Names?

Hello! This takes place in a fantasy-type world, where longer names go to royalty and shorter names to common people. The main character, a common girl, still needs a name. I’m thinking of [name_f]Freya[/name_f], but that might be too frilly. Names for other girls are: [name_u]Arden[/name_u], [name_f]Greer[/name_f], [name_f]Nimue[/name_f], and [name_f]Willa[/name_f]. Thanks for your help!

[name_f]Sienna[/name_f]? [name_f]Cressida[/name_f]? [name_f]Maeve[/name_f]? Drei? Larken?

I’m not entirely an expert on medieval or arthurian names, but these are some options that I could find:
[name_f]Mary[/name_f]
[name_u]Jean[/name_u] / [name_f]Jeanne[/name_f] / [name_u]Joan[/name_u]
[name_f]Kat[/name_f]
[name_f]Enid[/name_f]
[name_f]Alice[/name_f] / [name_f]Alys[/name_f]
[name_f]Bess[/name_f]
[name_f]Ann[/name_f] / [name_f]Anne[/name_f]
[name_f]Mare[/name_f]
[name_f]Thea[/name_f]
[name_f]Aphra[/name_f]
