My experience is that 'ls' and the like are fine once you've used them a few times. 'list-files' would just be more typing, and even with tab completion there's probably other things to list so muscle memory would end up at [l] [tab] [f] [tab] or something like that.

The one that constantly trips me up is 'which' vs 'where' but that's for a different reason.
