So far I have only used \setupbodyfont[xits,10pt], but found no info about how to specifically selecting fonts for the different modes or ranges.

Right, and writing the Unicode math characters in the UTF-8 source file, in part because they will be also used as such in the source code of a program. One can otherwise embed formulas using traditional TeX syntax.

Not anymore, perhaps, as some mathematicians seem to think of them as different semantic styles.

I used STIX because it came around, and, also, the AMS has been involved. It good there are other fonts, though.
