Use the 'scaling factor' setting in gnome-tweak-tool. On my 1920x1080
13" laptop (yup, I have one too) I set it to 1.3; adjust for your
taste. Firefox should respect that setting so long as you have
layout.css.dpi set to -1 (which is the modern default), though I'm not
actually sure if that works on Wayland. You can also set a 'minimum
font size' in the Firefox advanced font settings, though even that
isn't universally respected, I don't think (web font rendering
is...complicated).

Setting a minimum font size in Firefox always works in my experience;
however there are multiple "minimum font size" prefs in Firefox
depending on the language a web page sets via the lang= attribute
(usually for the <html> element). To cut to the point you can set the
minimum font size for each language by changing the language in the
"Fonts for" drop-down list in the Firefox fonts settings dialogue
(Preferences -> Content -> Advanced).
