Throwing kunai or shuriken isn't shuriken jutsu tho. It's more to it than that And Sakura never shown that ability. Boruto knows how to throw shuriken but Sasuke still taught him shuriken jutsu.
I'm not really sure what the specifics are for shuriken jutsu, but what Sasuke taught Boruto is curving his shurikens to hit a wide arc. Sarada hasn't showcased that feat, like not even in the Anime. Her shuriken feats usually consistent of hitting targets at pin point range or getting them in a fancy manner. But even then, there's no real specific definition of what entitles 'true' shuriken jutsu and what is just 'shuriken throwing'.
Sarada uses punches and kicks in her taijutsu Sakura only punches or punch the ground. I haven't seen Sakura kick not once since part 2.
Amma be honest with you. Ikemoto's style is different from Kishimoto's. In Kishimoto's, Sarada fights like Sakura completely. Punches and all. However Ikemoto incorporates more fluid motion. When Sakura gets an inevitable fight scene when Konohagakure gets attacked, she's not going to be only using punches. Her style will also be incorporated into Ikemoto's and she's going to punch and kick too.
oruto fight like Naruto but it's more fluid due to how his kage bunshins follow.

I'm just saying that their fighting styles are heavily based on their parents. Whereas Boruto is more like Naruto than Hinata, Sarada is more like Sakura's than Sasuke's.
I implore Ikemoto and Ukyo trying their best to give them slight variations and move sets to make them feel more natural. However overall I can't shake the feeling that when I see them fight, this is just another Naruto or Sakura. The same with Orochimaru's spawn.
There's really only a few ninjas in Boruto that have unique fighting style to the T. That bubble guy user has one, for example. Highly underrated and lame, but it's different.
