If you just want digital sampling conventions, there are generally two.
One based on subdivisions or multiples of the CD rate of 44100 Hz and
one on powers of two.

So, as mentioned, 44.1, 48, 96 kHz are common for music. On the low end,
32, 16, 8, and 11.025, 22.050, and sometimes 24 are common. Those two
sets give you something close to most targets. A lot of it depends on
your target hardware capabilities.
