You're describing a new chain making a new path on the plastic chain guide, it's literally cutting a new route.
When I got my first DID X ring chain it made what to me was a horrendous whizzing noise, but once a new path has been worn in it will slowly disappear.
Chain jumping about on the centre stand is because there is no weight on the wheel, and the momentum of the wheel builds up speed but the chain won't let it go any faster causing the chain slap.
Both are normal and nothing to worry about.

More people are born because of alcohol than will ever die from it.
