vSphere to Proxmox Migration Questions

[TopHatProductions115]

I'm currently running ESXi 6.5u3, on a ProLiant DL580 G7. I'm considering migrating to Proxmox VE, on a ProLiant DL580 Gen9. My initial plan, of migrating to ESXi 8.X instead, has been thrown into uncertainty by Broadcom's most recent changes. I've read through the migration and ZFS documentation a few times, but still have a few unknowns to address.

1. My initial (ESXi 8) plan involved a TrueNAS Scale VM for managing mass storage. Would there be any benefit to me using that anymore?
2. Some of my VMs use RDMs, due to limitations of my current setup. Can these VMs be migrated? If so, how?
3. Has anyone successfully used PCI/PCIe Passthrough on a DL580 Gen9?
4. Is there any official documentation on TPM passthrough or vTPM?

Sorry if any of these questions are dumb. Trying to address as many potential pitfalls as I can, before I attempt migration.

I've red that before. Are you suggesting that I convert the raw LUN to a virtual disk first? If so, I'd have to use the DL508 Gen9 for that task. The G7 was unable to create/use virtual disks of the size I needed, when I initially created the VMs.
