“does the lead developer prefer cheddar or brie” Quite right but given I live in Somerset (UK) I can have both: Cheddar is in Somerset and where the eponymous cheese originated and quite a lot of brie is produced here too - it's not the French original effort but rather good.

I have quite a lot of customers that we have migrated from VMware to Proxmox. Some of them are rocking zfs instead of vmfs. Mostly these are Dell servers. Proxmox with zfs seems to be more aggressive about disc failure warnings, which I think is helpful.

Pick what OS works for you.
