I am using a free service. Downside is that the 2.5 GB will expire there after
48 hours. Files from a Parrot Anafi drone flight are here:

It would have been easier if you included only the images that belong to
the panorama. At least 1/3 of the jpg images don't.
As was to be expected for an aerial panorama the images suffer from
severe parallax. They can't be used to say anything about lens
correction. Lens correction optimization is only possible, if the camera
and lens was rotated exactly around the entrance pupil of the lens, the
no-parallax-point.
If the images don't align it's not the lens correction model which is to
blame, it's parallax! Even worse: As soon as there is parallax the
optimizer will try to use lens correction parameters to minimize control
point distances for points that are misaligned due to parallax.
Nevertheless it should be possible to stitch a nice panorama, you have
plenty of images with large overlap and good features to choose from in
order to avoid alignment problems.
The lens should be treated as a full frame fisheye, though. Otherwise
the b parameter gets too high.
