Wayland only added support for fractional scaling a couple months ago, it will be a while before we see it standardized in desktop settings and app libraries (maybe longer for Electron). GNOME is certainly a tweak-lover's nightmare though, I'd recommend giving KDE a spin if you're brave. Qt applications and KDE should recieve fractional scaling support much sooner than GNOME (patch is already written/submitted), and generally the settings menu on that desktop is much more granular.
