Due to the large number of CAD programs in use, standards for layers, colors, linetypes, etc. varies widely, and probably will continue to. As for file formats (DXF, DWG, etc) these have become industry standards and any software manufacturer who fails to accept them does so at his own risk. Dimension styles, too, vary from program to program, but there has been some degree of coordination with Autocad's dimension standards, I think. Since Autocad dominates the field (except in Europe, Kevin), there has been some effort on the part of other CAD software manufacturers to accomodate Autocad's standards and conventions. Still, Autocad, itself, is very flexible in some regards, and customizable. This means that graphic standards tend to vary from firm to firm within the industry. I'll say this, though, as one who has spent the first 12 years of his career drawing by hand, the variation from one firm to the next has been greatly reduced by the advent of CAD. Before CAD, there was tremendous variability, even within the same firm, let alone the industry as a whole.
What you'll be using as your CAD standards still depends in large part upon the firm you're working for. You'll adopt their standards while you're with them, but if you go to another firm, don't be surprised if their layers, colors, linetypes, or even working procedures are different. I've worked with companies that favor a strict Autocad Model Space/Paper Space environment, for example, whereas, others prefer to eschew Paper Space altogether and draw everything including the sheet border in Model Space.
