Maybe looking for the answer in England isn't the right place.
In terms of England voting Leave and Scotland voting Remain, I tend to think it's just a big fish/small pond thing. With England being ten times as populous as Scotland, their relationship within the UK has England entirely dominant but in the EU context that changes. Yes, Scotland is just a minnow in that large group but there's no single big fish which gets everything its own way.
That's why I suspect slogans like "take back control" would have less traction North of the border, where they have an element of "give England back control".
