What’s the difference between archiving a conversation and deleting a conversation from Messages?

Archiving a conversation will hide it from your messages view, while deleting a conversation from Messages permanently removes the entire conversation and its history. To archive a conversation, go to your main messages page and click the "x" next to the message. The conversation’s history will be preserved, and you will still be able to find it later. If the same person sends you a new message later, the archived conversation will reappear, and the new message will be added to it.
