I can't really tell about leaf arrangement, but it makes me think Bradford/Callery pear. Are there any thorns?

Yes. Callery Pear was my immediate thought. Leaf arrangement is alternate.

Something turning orange that late, at least around here, are always Bradford pears.

Yes, they are late to turn. The ones round here are mostly still green.

The (millions) of Callery pear seedlings around here are the last to turn, but they are also one of the most colorful Autumn trees. The mainly yellow to orange in the photos was one question mark in my mind, even though I was almost positive with the ID. Here, they will be mainly a dark, vibrant red, with orange and yellow highlights. Gorgeous, in spite of being the equivalent of vertical kudzu.
