Current DNS best practice for AWS AD + Onprem AD hybrid with multi account multi vpc

Hi there's a number of AWS white papers that seem to be offer different guidance for our hoped-for scenario

see https://docs.aws.amazon.com/pdfs/whitepapers/latest/hybrid-cloud-dns-options-for-vpc/hybrid-cloud-dns-options-for-vpc.pdf#hybrid-cloud-dns-options-for-vpc and

In a multi account scenario where my AWS AD needs visibility, is the simple second paper with cond forwards the best way to do it ?
