Can these tags all be used to store the unique name of a photo or video?

I read the standards, but I didn't understand everything unambiguously.
I marked with a question mark those tags that I have doubts about.

exif:ImageUniqueID
Iptc4xmpExt:RegItemId - ?
XMP-exif:ImageUniqueID
XMP-iptcExt:DigitalImageGUID
dc:identifier - ?
xmp:Identifier - ?

I inconsistently composed the first message.

exif:ImageUniqueID (I currently know that EXIF standard does not fit for video)

Can these tags all be used to store the unique name of a video?

I can't really comment on this because it's not something I bother with and haven't looked into.

But it's always up to you what you want to use any tag for.  It's your data and your files. Figure out what tags the programs in your workflow use and adjust to use those tags.

Yes, I can do it, but I don't want to break the standards so that in the future I will worry less about collisions if my files fall under the control of some DAM.

I would advise you to pay attention to this. The security of files largely depends on the unique name, but the name can be corrupted. Therefore, after creating a unique name, you need to save it to metadata, but for this you need to determine the tags to save it to. Everything is very interconnected.
