If you are in Kubernetes land you probably want object storage and some kind of PVC provider. Not thaaat different from an old fashioned iSCSI/NFS setup to be honest, but in my experience different enough to cause friction in an enterprise setting. You really don't want a ticket-driven, manual, provisioning process of shares
a PVC provider is nice, sure, but depending on how much you need/want simplest cases can be "mount a subdirectory from common exported volume", and for many applications ticket-based provisioning will be enough.
That said on my todo-list is some tooling to make simple cases with linux NFS or SMI-capable servers work as PVC providers.
