2 OSD each node or only 2 OSD? You're breaking CEPH's philosophy. It's designed to be used with at least tens of OSDs. You can use any old/cheap drives. Just more-better.

For 2 drives maybe better use DRBD.

If your system SSD is fast enough, then why not? PVE itself not uses much bandwidth on it.
