This answer is sort of in between a glorified comment and a full answer, as your question invites opinion.
You don't need to follow any standard when making commit messages in Git. The primary purpose of a commit message is to leave information about what happened in your commit. It is the presence of useful/helpful information which is key here, rather than some set of codes which are used. Many organizations use their own templates for commit messages. But again, it is up to you how you want to record information here.
Update:
The Angular standard codes might be helpful in a way, in that they promote making separate commits for logically different types of tasks. For example, it would loosely enforce that bug fixes, refactors, and feature additions all come in as separate commits. In this sense, a standard is useful, but what I said above about having good commit etiquette still stands; include helpful information for best results.
