is it a problem that the device class for all my disks is SSD even all of

handles NVME disks differently internally?
No. When creating the OSD ceph-volume looks at
/sys/class/block/DEVICE/queue/rotational
to determine if it's an HDD (file contains 1) or not (file contains 0).
If you need to distinguish between SSD and NVMe you can manually assign
another device class to the OSDs.
