I have the same problem.

GNU Emacs 29.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.20, cairo version 1.16.0)

$ xrdb -query
emacs.font:	DejaVu Sans Mono-12

/tmp/test.el:
(custom-set-faces
 '(default ((t (:family "DejaVu Sans Mono" :foundry "PfEd" :slant normal :weight normal :height 120 :width normal)))))

emacs -Q -nbc -l /tmp/test.el
shows incorrect font

font-use-system-font
=> nil

(face-attribute 'default :font (selected-frame) 'default)
#<font-object "-PfEd-DejaVu Sans Mono-regular-normal-normal-*-13-*-*-*-m-0-ISO10646-1">

but after applying the following patch I get correct fonts:

(face-attribute 'default :font (selected-frame) 'default)
#<font-object "-PfEd-DejaVu Sans Mono-regular-normal-normal-*-16-*-*-*-m-0-iso10646-1">
