Shonen anime writing is not something anyone should strive to emulate, unless it's purely the bones of how those narratives work.
Even then, the issue isn't that Jaune is more interesting or has more going on. It's that he actively removes Ruby's reason for even existing. It's less like a Shonen case where the side characters are overall more interesting, and more like a Shonen where the side character is the protagonist and the protagonist might as well not even be there.
Like at least Naruto gets to actively fight the bad guys, has a motivation, and is the driving force of the narrative. Ruby is... just there. Any time she should be in the spotlight Jaune is awkwardly handed the reins instead.
Best example is the end of V5. We've had an entire previous volume of Cinder seething and wanting revenge against Ruby for searing out her eyeball. Instead of that, when the two are finally in a room together, Jaune takes center stage and the two don't even acknowledge each other. Jaune gets the big moment of conflict, Ruby is barely even a footnote.
