git tags are more lightweight than they seem. It's why the UX defaults to not sharing tags, with the idea that you may need/want local-only tags. They also share the same "namespace" that you could have tags like `myname/some-personal-tag`. (I've used `project-name/v1.2.3` style tags in monorepos rather than solitary versioning the entire repo.)
`git tag -d` deletes tags and `git tag -f` moves them (forces them to change).
For the most part whether you prefer a branch or a tag for temporary marks is an aesthetic choice, though the twist is maybe using annotated tags. The annotated tag allows you to leave a commit message for yourself why you made the temporary tag in a way that you can review later. Just like optionally adding a stash message (which also reflects why stashes work under the hood more like tags than like branches).
