You seem to be arguing more for reigning in the wizard than bolstering the fighter -- which i completely agree with, btw. I think the reason that people view the wizard as too powerful and versatile is that no one actually enforces the limitations on the class very well. They rest too much. they don't pay attention to components (of any sort). They don't focus on or enforce the limited choice aspect of the wizard's versatility. They don't target them in combat with intelligent enemies (kill the cleric first, tho).
I'm not saying there aren't ways to make the various fighters more versatile or interesting, but we are talking about comparisons, in my experience and opinion wizard dominance comes primarily from lax GMing.
