I find it hard to find a comprehensive overview about what kind of citation styles there are, and what should be taken into consideration to choose one.
It seems to me that the most important factor is when the journal/conference requires a specific citation style. Another factor is that it might be better to use what the people in the field are used to. But what advantages are there for different citation styles, apart from the fact that some are more established?
E.g. I see that numbered citations sorted by occurrence make it easy to find the citation listed in the bibliography while reading the paper from front to end. (Author,Year) citation styles allow the reader to recognize names but could possibly be ambiguous when an author published two papers in the same year. Why aren't both approaches combined to keep the advantages of each, and cite in-line with
(Name Year )?
