Are server admins able to selectively modify user’s content? Do they have the power to selectively edit, move, delete etc.? Or does the collective federation prevent a single bad actor from taking authoritative control?

Absolute. If you want to maintain control yourself you need to Self-Host.
Could this be solved by signing every post, and comment made by a user with a key that only that specific user possesses? That way, if a post is modified, it will no longer match that user’s key and it should therefore no longer be trusted.
Sure.
