raidz1. No issues so far. I’ve had some prior experience with zfs from work, so moving to it was a no brainer.
I’ve been using unraid for a few years. Super happy with it. Recently migrated from using their normal array to zfs since I got a hold of some enterprise SAS drives.
Man, the US is weird sometimes. I don’t think I’ve ever had a data cap on my home internet.
For an enterprise I would suggest working with a nextcloud partner. Unless they have a sizeable internal IT team of course.
Cloudflare tunnels! I use it to expose my nextcloud server to the internet. Works flawlessly.
^ this I selfhost nextcloud behind cloudflare tunnels. Super easy to set up and ssl is handled by cloudflare.
