Answer 1

if the height is set to auto it will automatically set its height to allow its content to be display correctly.

And fit-content is mostly used for the box content. If you set the fit-content it will use the full available space but never more than max-content.

Both are the same in such a manner.

Answer 2

I think fit-content would be for the specific parameters you set for specific elements and auto would be the machine sizing based on the parent element or the general default settings of the browser.
