Good Evening, ESXI won't support either raid solution as software raid isn't supported. ESXI has a very narrow list of supported hardware so I typically never recommend it for a home lab. Unless you really need ESXI I would suggest looking at running KVM on either Fedora or Centos. Another option is to look at Citrix Xenserver and perhaps leverage MDADM but I am not sure that is a supported solution either.
One other solution if you happen to have either a spare machine or a NAS floating around is to use ISCSI but again that is additional expense.
As for the UEFI comment, all of my ESXI and Xenservers in production are using ESXI as it leverages a lot of functionality and speeds up the reboot process.
Thanks
