Yes, the XYZ mosaic optimisation will resolve quite extreme parallax errors,
but only for features on a single flat plane in the scene.
In this case your ground is close enough to being planar, so Hugin can fix
parallax for all photos, not just the nadir.
By default this plane needs to be
And this is what the optimiser tab looks like:

Oops, Typo: the average cp dist was 0.6.

It shouldn't matter how you create the control points. You don't need a
huge number, but they should be nicely

Your stitching problems are almost certainly due to parallax. While you
would normally set up the camera such that it rotated about the entrance
pupil of the lens to avoid the effects of parallax, it's a sad fact that
for a fisheye lens the apparent position of the entrance pupil varies
