I live on the 28th floor in Manhattan and have double-glazed windows that face south. Which film would best preserve view, cut heat/glare?

There is a product on the market called Enerlogic which is extremely effective at reducing heat gain and glare while adding insulation value to the double-glazed window to make it perform like a triple-glazed.

We recently installed this film on several large windows in our office to test it, and it has performed well.

You should check and make sure the building owner/manager will not have an issue with you adding a film, as most will change the appearance of the glass tint or color from the outside.
