Assuming you are talking about plot styles, These are usually based on your needs for plotting and workflows and client expectations. Since you are the ultimate arbiter in your situation, you can set them to what ever you want.
If you are looking for a particular standard, it may depend on what you are drawing and what standard organizations are involved in that trade or practice. AIS, ISO, PIP etc etc all have standards which would be a good place to start.
Another thing to consider is that if you ever plant to make your hobby a reality you local municipalities may have standards that need to be followed if you want your plans to be used for permitting. Those you would have to check with your local organizations.
The general idea is that the pens (in the days of board drafting) that were different sizes had different colors associated with them so you could just find some of those pens and adopt their sizes.
Wiki has a good list of some standards organizations and some basic ideas for line color thickness.

Line-thickness
plot: 0.13 mm Gray, 0.18 mm Red, 0.25 mm White, 0.35 mm Yellow, 0.50 mm Magenta, 0.70 mm Blue, 1.00 mm Green. In AutoCAD usually parts to be printed in black are drawn in 1 to 7 basic colors. Color layer: Green-Center, Magenta-Measure of length, and Blue-Hidden.
