If he took them while he was still President it was perfectly legal to do so in any manner he chose. His mere act of doing it made it official policy because that was his unique Constitutional power. The next President can create new policy, re-classify information, etc. The only real risk is if Trump perjured himself or something about the docs when asked. All of his property is secured by the secret service. The idea that anything at Mar-a-Lago was stored in an insecure way is preposterous on its face.
