Background info in both FFX and XII pretty much show that people do use magic for building things like the Spheres or the flying cars in Archades, so you have that.

FFVI actually has a very minor shout out to the idea the Empire was actually allowing magical augmentation to civilians for everyday use, such as the one child who was given Cure magic. Normally magic is just shown to create really cool engineering achievements as opposed to say watching a wizard to use Fire to cook or Float to help clean the floors. The closest you get is Matoya's Fantasia Brooms that clean her cave.
