In my opinion, a good user story for team to work with should be done in the "INVEST" format. But, to remind the benefit of user story, it should follow 3 C's style. If the user story doesn't have card, conversation, and confirmation, it loses the point of user story.
In my team, we try to write user story using "INVEST" (with user story format as a/I want to/so that), then we will have "conversation" about it. During this session, we know that the "card" is in the good shape or "INVEST" or not. Then, we "confirm" that the card is good to go for the sprint.
Some teams don't focus to make the user story to be "INVEST" or in user story format because they focus on "conversation" of the cards. So, the format could be anything that team agrees on.
From time to time, your team will figure out what is the best user story format for them. It will just happen naturally.
So, I think there is no silver bullet for this. Just remember that the user story or the item (any name you wanna call) is something that your team agrees on and is comfortable to work with it. Making the decision is not up to one person but team.
