To me, a "deep dive into a single thing" is a more apt description of a PhD. A minor indicates a small concentration of coursework in a field separate (but possibly related) from your major. Many students also double major, which effectively results in graduating with two degrees. Frequently, these majors are related (like, CS & Math), but sometimes they are unrelated (I know someone that did CS & PolySci). It's hard to quantify the benefits of a minor or a double major. Presumably, it looks better to perspective employers and may give you a wider range of employment opportunities depending on which fields you selected.
