Self-hosted alternative to synology drive?

I moved off a Synology NAS to a self-managed machine and one thing I still struggle to replace is something like a synology drive. Here are my requirements:

• server side store data in a plain FS (I want transparency)
• client side (windows), it must support VFS (download files when needed, support offloading of large files)
• having snapshots of data is a must

I have a 40gbit uplink to my desktop, so if everything else fails I’ll just use samba with zfs snapshots exposed to VSS, but we’re talking some large files still (think several hundreds of MBs) and I’m not sure Blender will be happy working off a network disk.

I’ve been pointed to next/own-cloud previously, but they don’t seem to cover my use case, I think. Should I actually try one of those? I browsed around owncloud's storage bit (which is written in go), and it seems mostly fitting, but I’ve been told I should steer away from ownCloud towards nextCloud.
