No, you want to customize fontset-default.

Use 'prepend as the 5th argument of set-fontset-font, for more

Please describe how you tested that.

Fontset customizations are independent of faces, so I don't think I
understand what you mean by "picking customizations of the default
In general, if the default face's font supports some character, Emacs
will use that font, so I don't quite understand why you need to
customize your fonts just to have characters displayed by the default
face's font. It shouldn't be needed, if the font really supports

There's no such thing. That's not how fontsets in Emacs work.

Maybe there is, but I don't know how, and frankly doing that makes
little sense to me. Emacs was designed to display every possible
character by selecting a suitable font; forcibly displaying some
characters as boxes is against its design.
