I would shoot open gate anamorphic, you want to have as much height on the sensor and squarest shape output to maximize resolution and minimize how much cropping of the sides you will need to do yielding a much wider FOV. If you shoot 16:9 you will end up cropping away half of your horizontal resolution and end up with the same FOV as if you had just shot spherical from the begining.

If you are shooting with 2X anamorphic lenses for a cropped 16:9 image, then you are effectively using .89 : 1 area of the sensor, very vertical, and doubling that (to remove the 2X squeeze) to 1.78 : 1. So there isn't much reason to use anything other than the 6:5 mode, which records close to max height of the 4:3 sensor but not width, unlike Open Gate (Open Gate is only slightly taller). See:
If you are finishing to HD, not UHD, there is an option called ProRes 16:9 ANA which does all of that work for you, crops 2X anamorphic to 1.78, etc.
ProRes 16:9 HD Ana. is for situations where the look of anamorphic lenses is desired but the end product is full 16:9 HD without letterboxing. This mode also supports recording speeds up to 120 fps.
