Is the OP's install missing a bunch of MIME entries or something? I can't reproduce the examples given for xdg-mime on Fedora 34, e.g.

  $ xdg-mime query filetype file.docx
  application/vnd.openxmlformats-officedocument.wordprocessingml.document
  $ xdg-mime query filetype file.xls
  application/vnd.ms-excel

Can't reproduce any of these on Arch either, mine is definitely checking the contents of the file as it saw an empty file titled "file.pdf" as "text/plain" and a .doc as "application/msword".

Fedora 34 is as bleeding edge desktop as it can be.

Maybe you have more recent xdg-utils version?

I run 1.1.3 here.

I also have 1.1.3.

Maybe what's missing is the libreoffice package? It seems like all these types are provided by /usr/share/mime/packages/libreoffice.xml on my system (which is read by update-mime-types).

Arguably this is a common enough format that you shouldn't really need libreoffice installed to have it, though I would think any other office program would have it. I think /etc/mime.types serves as the ultimate fallback, though it doesn't have entries for libreoffice file extensions on my system.

I will look into that, thanks.

xdg-utils does not use /etc/mime.types; that file is used by Apache httpd, CUPS, and various other programs though.
