I think the eye and hair colour categories are useful, but I don't think there's any point of adding religion since you can count on one hand the number of characters in the MCU who have expressed their religious beliefs.

On the Game of Thrones Wiki we have a section in the character infobox for their religion and in the region infobox for the region's dominant religion. There are also categories for the religions, but these are reserved for members of the clergy as well as locations and practices associated with the religions. Since religion doesn't play anywhere near as big a part in the MCU, I don't really see any point.
