Main Character Name Help!

I am currently writing a story featuring a female main character. The story is set in a dystopian society in the not so distance future. (So names that are too futuristic are not ideal).

She is 16 years old living with her older brother. Their parents are dead. She has one close friend. Her brother is taken by the society. She sets out to find him.

A few words to describe her personality:
Strong, determined, passionate, hardheaded, and, as the story develops, becomes more opinionated

I really like simple names such as [name]Alice[/name] or [name]Lucy[/name](these are the baby names my fiance and I have chosen so I prefer not to use them)

Surname suggestions are not needed, but appreciated!

I’ve always imagined a girl with that type of personality to have a unisex/boy’s name or a name with harsher syllables:
[name]Kate[/name] (as a nickname for a [name]Kat[/name]- name)
[name]Teegan[/name]/[name]Teagan[/name]/[name]Tegan[/name] (TEE-gan)
[name]India[/name]/[name]Indigo[/name]/[name]Indiana[/name] “[name]Indy[/name]”
[name]Lucia[/name] (I know you said that you would prefer not to use [name]Lucy[/name], but I think [name]Lucia[/name] really fits an opinionated girl) (loo-see-ah)

That sounds very cool! I really like [name]Alice[/name] and [name]Lucy[/name], and I would totally feel the same about not wanting to use them.

I could definitely see a pretty name but with a simple, one syllable nn.
[name]Isadora[/name]/Is… I really like this but I could see ‘Is’ as very confusing/annoying.
[name]Juliet[/name]/[name]Jules[/name]…not sure about this one.

I could also see something a bit surname-y or unisex.

Or maybe something a tad edgy.
[name]Scout[/name]…Although I can’t think of anyone but [name]Scout[/name] [name]Finch[/name], which isn’t really a bad thing?
[name]Zelda[/name]…It kind of has a futuristic sound to me, but I didn’t want to rule it out because it’s definitely older and awesome.

I personally am leaning toward a nn option, but I REALLY like [name]Thisbe[/name] for this character!

The idea of a unisex/boy name or surname is appealing to me more each time I think about it.

I like [name]Sawyer[/name], but as with [name]Scout[/name], it reminds me of another character ([name]Tom[/name] [name]Sawyer[/name]).

Feedback on the names:
[name]Addison[/name] or [name]Addyson[/name], maybe nn [name]Addy[/name]
