I'd use ceph then. Scalability is something ceph is just made for, and
maintainability is also really not to bad, IMO. You can do CTs and VMs on
normal blockdevices (rdb) and also have a file based shared FS (cephFS) both
well integrated into PVE frontend/backend, which other shared storage systems
aren't.
