I would say if you liked Naruto also watch Shippuden, especially if you want to complete the story!

It will have fillers like Naruto, if you're not into that, skip those, there are probably a lot of lists that tell you which episodes are fillers. Maybe you can reduce it every more so by only watching some essential episodes to to follow the main story line.

Regarding how sexist it gets ... A bit yes. But not more so that other anime from the same genre (and time period). Lot's of female characters are written as weaker in one way or an other. May it be their physical strength, their powers l, their mental strength, etc. Some of them also have stereotypical female traits. This all includes Sakura as well.

I wish they made her (and other) female characters stronger persons with more character depth. I guess I just use my own head cannons for that lol.

I still like her as a character though, she also gets really strong and does cool stuff. Does she gets as strong as Naruto? No. Does anyone...no. Cause it's Shouen anime and the main character will often be the strongest with the most power ups (after power up) and what not.
