Proxmox + QNAP TS-1655 + Drive Planning

I am wondering how best to use the drives on a fully populated QNAP TS-1655 device (12x 3.5" bays, 4x 2.5" bays and 2x NVMe slots) with 128Gb RAM and a 10GbE adapter installed.
The intention is to install Proxmox as the host OS to manage all VMs including TrueNAS Core to provide network storage and file sharing.
Has anyone else setup a similarly configured device in terms of available drive bays and slots?
My initial thoughts for disk deployment are as follows:
2x 480Gb Samsung (Enterprise) SATA SSDs as a RAID1 mirror for the Proxmox OS (- I am aware that capacity-wise this may be overkill but the cost is negligible over smaller capacity enterprise drives).
2x 1.92Tb Micron (Enterprise) NVMes (if I can get hold of more than one!) also as RAID1 mirror to run the VMs from.
12x 12Tb WD DC HC520 (Enterprise) HDDs for data storage pool(s).
Plus to populate the two remaining 2.5" hot-swap bays:
2x 1.92Tb Samsung (Enterprise) SATA SSDs
Should these be used for read and write caching, if my initial thoughts are good?
Are there other, possibly better ways to deploy the drives? Any suggestions would be greatly appreciated.
