The only thing I disagree with him on this is that function length doesn't matter. Longer functions do tend to be harder to understand. I will admit that sometimes a lot of helper functions can make it harder to piece together, so you can overdo it, but usually putting one or two of them back into the main function gives a very readable function. So I would tend towards more smaller more decomposed functions with descriptive (but concise as possible) names by default. This is very different from old-fashioned C standards, which I feel are very outdated for modern tooling and hardware. It's definitely important to have formatting standards to avoid arguments about that. But you are never going to completely eliminate stylistic things because part of that is function decomposition or intersects with the actual substantive design. Because some people feel quite differently about function size for example.
