I think when they are first being trained it is best to do it inside. Most pups don't have all their shots yet and shouldn't go outside. But either way, I don't think it is about inside or outside, but rather teaching them the "potty" command in itself. Once they know what "potty" means they will go wherever you tell them to. Just like ourselves, we can go if we make ourselves go, even though we can wait a bit more.

Uni goes inside, in the sun room, so it's not directly in our living space. But when we go on walks, she will go outside too if i tell her to, or if she wants to mark something.

Before at our old house, when we would come home from work, she would go pee in the downstairs bathroom, then run upstairs and go poop in the upstairs bathroom! Also during that time when we were visiting MIL on the weekends, early in the morning she would get out of bed and go in the (empty) closet where her pads were and go in there, then come back to bed. i wouldn't even have to take her to go potty, she would take herself.
