It is certainly a good idea to use PARTUUID when possible.

In general yes. However, my understanding was that it works only with a
GPT partition table, because only the GPT partition table can embed a
unique identifier per partition, not the old MBR partition table. But
apparently this disk-signature thing allows to embed a disk-wide
identifier, not a per-partition one, so it works only when there's a
single partition ?
Best regards,
Thomas
