why you might choose any given type from that header over any other one
would be because of its use in a library function, and there should be
manual pages for all the standard library functions which document the
types they're intended to take.

For documentation of the various system-specific conditional macros used
in <sys/types.h>, I recommend feature_test_macros(7) (or ftm(7) for
