Swift is an Openstack project so sure it's good to use with Openstack or
even on it's own. It is Object Storage (like AWS S3). If you want volumes
you'll want some other system like Ceph, some NFS server, etc. Proxmox is
capable of deploying Ceph and that's what I was referring to.

You can easily import those images into Glance (Openstack image
service);and then launch instances using them.

This is mainly a matter of your use case. Openstack is complex; more
complex than Proxmox by quite a bit. It is also extremely powerful and has
many projects to provide lots of cloudy services. Many of those services
are analogous to ones found in AWS and other public clouds.

It is well suited to orchestrate large numbers of instances, volumes,
networks, etc. across many hypervisors,

Proxmox, as far as I recall, is more of a straight virtualization platform.
I also recall it being fairly simple and reliable. If it meets your needs,
don't complicate your life.

You may want to sign up for a trial at an Openstack-based public cloud
provider to get familiar with the functionality before committing to
building your own. You can find a list here:
