Visit the house as much as you can while it’s being built so that you can catch things that go wrong (which there will be).

Absolutely! I would go as far as saying "plan to be there yourself most of the time". Builders make a lot f stupid mistakes and assumptions - it's much easier if you notice they are putting the door so it blocks the dishwasher, and can shout "hold it!" than if you discover it after you have moved in.

This goes especially for non-standard or unusual stuff (like ethernet).
