I think Dr Soong designed Data to be as human as possible (minus Lore's little bugs), so unless required, he naturally limits the use of his non-human abilities. Of course, working in Starfleet means situations inevitably arise where those skills are needed. But he doesn't deploy them unless they are required.
I think this is probably the correct answer. Although Data has been shown to use his non-human abilities in casual environments, such as when he was in the art class in "Masks" or when he built the temple for the boy in "Hero Worship."
