She has no one to teach her any Uchiha Jutsu's and the Jutsu's she can learn from Sakura at the moment would be basic, the more advanced onces require years of chakra control practice, and who knows she may never be able to master them, though if she is the daughter of Karin she might not even need to learn all that.
Besides she's not even a Genin yet, besides we saw with Obito, the Uchiha without the Sharingan are weak, soon as the Sharingan is unlocked they go super powered....It will be interesting to see if Sarada actually unlockes the Sharingan, as she'll be the first Uchiha female shown with the doujutsu.
We did see a female Uchiha with Sharingan, when Itachi was explaining Izanami to Sasuke
