i can only speak for myself, but i prefer to keep the objects large to begin with, depending on how detailed you want them to be and how small the object is in real life.
With a cm/mm object it is always difficult with the numerical input ala 0.00002 and I don’t like to build zoomed in 3D space.
It is also easier to make a large object small rather than a small object large, but that is just personal preference, there may be good reasons to do it this way.
