Over the past few years we have standardized on our fastener sizes, but so far we have not chosen a standard finish. For most SHCS, BHCS, HHCS, etc, the options for carbon steel bolts are either unfinished/black oxide/phosphate, or some sort of plating like zinc.

I tend to like the plating because of the corrosion resistance and nicer look. They are more expensive, and sometimes available in fewer lengths. What does your team use?
