In my mind you use many of those commands to perform actions in the repo or locally which are related.

For example: 'git reset HEAD~1' is something I use often, it is vaguely like 'git revert <last-hash>'. Therefore I see them as providing similar functions semantically, but not literally.

'git fetch' and 'git cherrypick' are again similar in my mind where one is pulling changes from a remote, while the other pulls a set of changes from one branch into another locally. This is not as good an example though, but I do think they have slightly overlapping concepts.
