It's not clear how north-south grid connections are supposed to address this. You can create a long-distance transmission line from New York to Florida, but it's winter in Florida at the same time as it's winter in New York. Can you create a long distance transmission line from New York to Brazil? Even if you could in theory, probably not in practice, and even regardless of the technical factors nobody is going to want that kind of cross-border dependency for something as important as heating.

On 21 December, the day is about 77 minutes longer in Miami than in NYC, and panels in Miami aren't going to be covered in snow.

Yes. $$$.

Spend enough (production is high enough for this, yes I have checked, it's just how much money you want to spend) and it could be from NYC to Perth Australia.

Also true. Unfortunately.
