Writing to many files and which fields are best practice

Couldn't agree more. This is exactly what I'm doing in my application!

The last thing i wonder about, and I wonder if I'm missing arguments for codepage or something, OR if it in fact is limitations in the tags: When I write the special Norwegian chars to the various fields, only these four were able to retain these correctly:

File: Comment: in15Descriptioøn_ÆØÅ(C)æøå
IFD0: Image Description: in15Descriptioøn_ÆØÅ(C)æøå

See a screenshot of my inputs/command/output here:
(will be automatically deleted in 6 months)

This is the command (you can probably not see the special Norwegian characters):
-DateTimeOriginal#=1900:01:01 00:00:00
-XPSubject=in7Åse, in8Kjærsti, in9Bjørg, in10ÆØÅæøå
-MWG:Copyright=in13Cøpyright ÆØÅ(C)æøå
-MWG:CreateDate="2022:11:07 15:45:25"

The (sorted & selected) output is:

Anything I should do differently to preserve the special characters?

(just noticed that I can attach images here :- )

If you are passing UTF-8 characters to ExifTool then you don't need to specify a -charset option, and the characters will be properly written to XMP.  If you are writing to IPTC, you should add -codedcharacterset=utf8 to the command, but only if the pre-existing IPTC doesn't already contain non-UTF8 characters.  See FAQ 10 for all the details.

...where DIR is the name of a directory/folder containing the images.  On Mac/Linux, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).
