Solved FONTS question...

PSP “enumerates the font files in C:\Windows\Fonts directly rather than querying the Windows font API, so the hidden flag is simply ignored”

If you 1) delete the font files or 2) move them out of that folder (possibly add a .bak after the extension, but this is just a thought on my end), PSP won’t show them anymore.

“The same issue is confirmed for paint.net and other apps that don't use the standard Windows font common controls.”

Can't say this issue of fonts has ever bothered me -- the only Font that seems to be missing from the standard W11 install is the Baptismal Font.

Hidden Fonts still show in all Office applications too.
