I know of a few people in a Discord that filter out anything bigger
than /16 routes, would this be wise to implement as a best practice?

once upon a time, a very large provider took two /8s and announced as a
/7.  a vendor who thought a /8 was as short as they would ever see had
routers fall over in a receiving large provider.

do not hard code social theories.  remember 640k.
