My question is what determines where that peak occurs?

Mathematically, it will be where the SWR circle is tangent
to the reactance arc.

That is not in general true; do you have reason to believe it's true
for the impedance of a dipole? Consider what happens when you change
the reference impedance for the SWR measurement.

The higher the SWR, the higher the
maximum possible reactance and the closer it is to the
anti-resonance point.

What's the reactance at the anti-resonance point? Is highest SWR at
anti-resonance, or at maximum reactance, or at some point between?
