Explanation
By using an SCP with the aws:ResourceOrgID and aws:PrincipalOrgID condition, you ensure that only IAM principals from within the same AWS Organization can access the S3 buckets. This SCP restricts access from any IAM principals outside the organization while allowing access within the organization. This approach meets the requirement without affecting existing permissions within the OUs.
