SOCKS4a is a commonly used name. SOCKS5a is not - best not to add any

Furthermore, a lot of people (me included) are under the impression
that the default for 4a and 5 is to do DNS through the proxy, so any
documentation should be very clear about any flags you need to use to
get expected functionality.
