I would like to try ESXI but once I come to the paid features, I may want to switch to XCP-ng or another one. I will be using ZFS.

I'm considering running ESXi on bare metal and then virtualising TrueNAS am wondering if this is the best platform if you want to have the most job opportunities while having all the home server fun.

I want to run my own cloud so I will be using NextCloud and also a media streaming platform to the TV.

Since I'll be using ZFS storage, how will I know whether to run a VM on ESXi or on TrueNAS?

Would use XCP-ng instead of ESXi?

There may be some other options or things I've missed. Thanks!

After reading from different posts that 1 bit memory errors are fixed but 2 bit memory errors are not fixed but they are only reported while using consumer grade CPUs and motherboards with ECC memory, I am wondering if I should continue with my build or whether I should change it to support the full ECC experience.

Currently, the CPU I am going for is the Ryzen 7 5700X and the motherboard is the Asrock B550M Pro4. I've already bought everything except the CPU and the motherboard: https://pcpartpicker.com/list/GysckJ

Is there a comparable alternative which makes full use of unbuffered UDIMM ECC memory and is it worth it? Or is there a different type of ECC RAM and setup that would work better for a server build? Thank you.
