The Long Island Railroad also goes to that Airtrain much faster and
lots of people take it. The NJ Transit train goes to Newark airport
via another airtrain and it's also quite popular.

How many of those people are visitors on their first trip to NY?

I haven't a clue. Probably depends where they're from.

Elsewhere in North America, the subway or local commuter train goes to
the airports in Toronto, Boston, Philadelphia, Baltimore, Washington
DC (National), Atlanta, Chicago (both airports), Dallas, St Louis, San
Francisco, Portland OR, Seattle, Vancouver, and probably other places
I haven't been to. In each case there's been plenty of people on the
train with me with suitcases.

First time visitors to the city, who would normally use a taxi?

Here in the US, the normal thing at an airport is to rent a car, not
to take a taxi. The distances are greater, and we have absurdly large
car parks. One time at a conference in Lyon (where there is a
convenient overpriced tram from the airport) a young guy from
California on his first international trip rented a car and attempted
to drive it around the city. It was pretty funny.

Atlanta's another metro system where people have said I was crazy to mix
it with the locals. It's a very deep seated prejudice.

I can believe it. The local snark is that MARTA means Moving Africans
Rapidly Through Atlanta. The communter traffic is horrible but
adjacent counties have repeatedly voted down MARTA extensions because
Those People could come to their counties. (It is my impression that
a whole lot of those people come as house cleaners and garden guys,
presumably arriving by magic, or more likely very slow buses.) I've
never had any trouble on MARTA.
