I’d say I agree to a point. I think Cloud is what makes the storyline what it is, but at the same time. I’d agree that his character could’ve been fleshed out a bit more in a lot of ways. Especially in his relationships with Aerith, Sephiroth and Zack.

And it’s further backed up by the change you can see in him when he learns the WHOLE truth and how he does a 180 as a character.

Like for example. I genuinely like Wakka from Final Fantasy X and think he’s a great character with a lot of development. He has a genuine albeit misguided reason to hate the people he does given his situation, his firm beliefs in Yevon and to not spoil an over a decade old game his brother’s death.

Plus he has a great character development point throughout the game that lessens his hate towards the Al bhed and even sees him developing a genuine friendship with Rikku and the other Al Bhed to some degree
