As @DanThomas said, the two For Each pseudo actions are not really actions at all, they are pre-configured actions (to make up for the fact that you can’t actually save pre-configured actions yourself (unless you’re quite ingenious). they are also there because it is easy for people not to immediately understand the concept of “any time you have a list of things, look at the For Each action” and/or realize that the Finder Selection and a Folder Contents is a “list of things”.
Aside from that many actions have multiple variants, and the name in the Action Selector is designed to lead you to the right action without having to put every possible action variant in the Action Selector. So the action selector has “Get File Attribute” rather than a dozen different specifically named actions.
