Answer 1

Pretty much every modern language that had wide use has its own coding standards. These are a great starting point. If all else fails, just use whatever is recommended. There are exceptions of course, but these are general guidelines. If your team prefers certain variations, as long as you agree with them, then that's fine as well.

But at the end of the day it's not necessarily what standards you use, but the fact that you have them in the first place and that they are adhered to.
