What's the difference between 'git rm --cached', 'git restore --staged', and 'git reset'

Question

I have come across the following three ways in order to unstage the files that were staged by the command 'git add'

git rm --cached <file>
git restore --staged <file>
git reset <file>

Their behaviors looked completely same when I ran those commands one by one. What exactly are the differences between them?
