One common plot element is the early access to the Sharingan. Since Naruto is born an Uchiha, he usually gets the Sharingan much earlier than in the original series. Another is the change in his relationships. His bond with Sasuke becomes different as they are now clan - mates. Also, he often has to deal with the Uchiha clan's secrets and history, which was a big part of Sasuke's story in the original but now becomes Naruto's too.
Well, a common plot element is the exploration of Naruto's new identity within the Uchiha clan. He has to learn about the clan's traditions and values, which he was not exposed to before. This can lead to some interesting internal conflicts as he tries to balance his old self and his new Uchiha self. Another aspect is how his Uchiha heritage affects his power growth. He may develop new abilities related to the Sharingan faster and in different ways. And his relationships with other characters, like Kakashi, who has a connection to the Uchiha through Obito, also take on new dimensions. For example, Kakashi might take a more personal interest in Naruto's development as an Uchiha.
Well, one possibility is that he'd have the Sharingan from the start. He might grow up with different training methods, more focused on Uchiha techniques. Maybe he'd be more of an outcast in the village not just because of the Nine - Tails, but also because of the Uchiha's reputation. And his relationship with Sasuke would be completely different, perhaps they'd be rivals in a whole new way, competing over who is the true Uchiha heir in terms of power and abilities.
Perhaps in this fanfiction, Naruto being born an Uchiha means he has a natural rivalry with Sasuke from the start. Since they both have Uchiha blood, they might compete not just for power but also for the right to be the true heir of the Uchiha legacy. Also, his Uchiha lineage could attract the attention of Orochimaru, who might see Naruto as a new vessel with the potential of the Uchiha powers.
One common theme is power. Since Madara was extremely powerful, fanfictions often explore how Naruto deals with this new - found power if he is related to Madara. Another theme is identity. Naruto has to figure out who he is now that he has this connection to Madara Uchiha.
One common plotline could be the mother trying to hide Naruto's connection to the Uchiha from the rest of the village. Since the Uchiha had a somewhat controversial history in Konoha, she might be worried about Naruto being ostracized. Another plotline could be Naruto inheriting some sort of special Uchiha - related power from his mother, which he then has to discover and master as he grows up.

A plot twist could also involve her relationship with the other Uchiha members. Since Naruto is known for her strong will and determination, she might challenge the traditional Uchiha ways.

But she could try to change that mindset within the clan, causing a rift between those who want to stick to the old ways and those who are inspired by her new ideas.
