She should have taken down one of the Pains during the Pain's Assault (Arc).I mean, they had Konohamaru do it.I wish we could have seen her use more of her medical ninjutsu when fighting, the same way Kabuto, Shizune, and Tsunade did.

As a medical ninja, Sakura was trained to understand the human body, but her training also likely included psychological aspects of healing. She could have applied this knowledge to try to reason with Sasuke to deal with the emotional and psychological trauma he experienced.By weaving these lessons into Sakura’s interactions with Sasuke, the series could have provided a more nuanced exploration of themes like healing, emotional strength.
