In Naruto Sakura doesn’t get a lot of screen time and isn’t a big force multiplier. She does some stuff and you get to argue about her capacity to be there against Kaguya or whatever, but she’s rather stunted as a character.

In the fanon they glorify her. No special family but still became the strongest kunoichi, she’s the best educated, etc. etc. It’s not that these things are necessarily untrue, but it’s certainly not focused or highlighted in the narrative.
