@scottalanmiller
The reason I was mixing md raid and ZFS was I didn’t think ZFS allowed other ZFS devices to be used under a vdev. To accomplish this, would one need multiple zpools ?

MD RAID can definitely do layers upon layers. But ZFS does this, it's how ZFS does RAID 10, for example, or RAID 60.
