Personally, I've found fractional scaling on Gnome makes the window furniture too large for my taste. I've settled on boosting the default font size in gnome-tweaks to 125% instead, which makes font rendering match the DPI of my monitor but leaves window bars / tool bars etc at a more sensible size.
