Matcha-gtk-theme VS Shades-of-gray-theme

I use one of the Matcha themes with a few modifications and the Qogir icons.

Your other option is to find a theme that has a slimmer look, that way you don't have to change the font size or anything else and let the theme take care of the padding. This theme comes to mind, although I haven't personally used it in a while. There's also Linux Mint's official theme Mint-Y, it might be in Pop!_OS's repositories (sudo apt install mint-themes) but there was a recent update that made the themes look much better, I'm unsure if this new update is already in the repos.

Matcha as well.

I use Matcha on just about every system. https://github.com/vinceliuice/Matcha-gtk-theme

You could use the Shades-of-gray-theme GTK theme, which has Firefox css tweaks to make everything dark and fit the theme (blank page, about:config, etc). It's also one of the best dark theme in my opinion.
