i think a good example is text size. My eyesight isnt horrible but it isnt great either so some small text can be hard to read for me. But in gnome in accessibility there is just a toggle for “large text” so i can either make all text fucking massive, or have it be normal. Other than that the most i can do is try to change specific font settings and fiddle with it constantly for each application lol. This could be fixed by just having a slider instead of a toggle in gnomes text accessibility options and letting you choose between a few different sizes.
