Itachi Uchiha was a complex and tragic character. He was a prodigy in the Uchiha clan. He killed his entire clan except for his younger brother Sasuke, which was a shocking act. But in fact, he did this under orders from the Hidden Leaf Village elders to prevent a coup by the Uchiha clan that would have led to civil war. He lived as a double agent, making himself seem like a villain in Sasuke's eyes so that Sasuke would grow strong enough to kill him and be hailed as a hero, thus protecting the village and Sasuke at the same time.
The key event was the Uchiha clan's planned coup. Itachi chose to stop it by massacring the clan. Another important event was his encounter with Sasuke, leaving Sasuke alive with the intention of making him strong. Also, his possession of the Mangekyou Sharingan which was related to his deep emotions and traumas.
The most important event was him killing his clan. This changed everything for him and Sasuke. Another one was joining the Akatsuki. It put him in a new and dangerous situation.
One idea could be a story where Itachi and Kushina meet in a parallel universe.

You can find such fanfictions on websites like Archive of Our Own or FanFiction.net if they exist.

Itachi's time in the Akatsuki was also full of intrigue. He constantly had to balance his true loyalty to the Leaf with his role in the criminal organization. And all along, his love for Sasuke was his driving force, even if it seemed like he was cruel to him at times. He wanted Sasuke to become strong enough to take revenge on him and in doing so, free himself from the cycle of hatred.
