'Well rooted' is most of the time relative and subjective but if the rooted cutting has good fibrous roots beyond those white brittle roots then,if I was in your place, I will move it 2~3+ quart pot and cover it with a plastic bag dome for a few days (for humidity) until the leaves are erect again and then gradually wean it off the dome if you see that the roots are sustaining the leaves OK. Then gradually introduce it to more light. Once introduced to sun light inside, direct sun light inside should not cause problem if you keep an eye on its development (i.e. putting it back in humid environment if you find that the root system cannot yet supply enough moisture to keep the leaves erect).
The sun light and heat inside the house depends on your location. In my location in Zone 5 I do not have problem in keeping established rooted plants in direct sunlight.
