Agreed. HiDPI is the way to go and we should appreciate Framework for putting that in their laptops instead of continuing the use of shitty 1366x768 screens.
Xorg is the reason why OP is facing the scaling issues. OP, try to force the apps to run on native Wayland if they support it but don't default to it. The Wayland page on Arch wiki has instructions on that. Immensely improved my HiDPI experience.
Isn't scaling to 200% the same as lowering the resolution to half? And you lose the high DPI for apps that support it too.
