1/2500 for skin, if there's something white in the frame I might knock it to 1/3200
I'm not in NY by the way, but ISO100 1/1250 f4 is always my starting point for full sun.
Of course, if you use a flexible converter and shoot RAW, the actual saturation-based ISO across cameras is around two stops. One camera might be 113 at "ISO 100" and another, 29.
It would be a shame for a person to expose "ISO 100" for 100 and lament not having ISO 32, when in fact, they can actually shoot at ISO 32 with "ISO 100". Just no room for specular highlights, but that is not even an issue in many scenes. Again, your converter has to flexible enough with your camera.
Try it; set your camera to its lowest ISO, and shoot a color-checker at sunny f/16 for a range of low ISOs, and see where the white patch actually clips or where your converter can't be tweaked to get color right. In most cases, you can drop to at least 80, and possibly much lower with some cameras.
This is less dangerous than TTL metering, because darker things on the weighted part of the meter do not cause over-exposure of the base-ISO RAW.
