I would definitely go with Nemera you can use the nn Nemy which is really cute and chic. I also loved the suggestion Nova, and if anything you can always go with Nymeria it has animal connections being that a direwolf was named that in GoT. I think it was a good move to take off Vida off your list, yes it is pretty and a strong name but not my favorite. Kenzie however is one of my all time favorite names but compared with Nemera which I have never heard of before this post has no competition against it. GO WITH NEMERA!!! despite the the prounounciation errors you may face, either way it is pronounced it sounds beautiful.
I love Nemera! It's so unique/intriguing and goes perfectly with Wilde.
I would choose Vida! It's gorgeous :)
I LOVE Nemera!
