Native here. I'd say only about 6 out of the 47 listed actually matter (Awasebashi, Urabashi, Kamibashi, Jikabashi, Tatebashi, and Neburibashi).
Most of these are only for formal settings. Honestly, I haven't even heard of some of them.
Aside from Tatebashi (sticking chopsticks in rice), they’re mostly avoided for hygiene reasons. As for Nigiribashi (clutching them in a fist), it just looks a bit strange for an adult to do.
