Raid layout for Asustor Flashstor FS6712X?

I have watched as many of the Level1 videos about ZFS and Unraid. (mostly ZFS)
I am contemplating an AsusStor 12 NVME drive all flash Storage box (need 10G)

Even though 12 x NVME, I will likely start out with 6 x NVME drives x 2Tb, and later add 6 x 4TB or 6 x 8Tb. (assumption, price will go down and capacity will increase)

Do you have a suggestion for a ZFS layout (vdevs? pools? boot off USB) for a device such as this.

I appreciate your knowledgeable youtube channel.

I am sure you know that it does not support ZFS out of the box… Anyway, I think, if speed is important, mirrored configurations would be preferable to parity based setups due to the hardware being farly conservative in the compute department.

Thank you. Appreciate your answer…
