IMO light-seconds is actually a really nice unit for interplanetary distances. 1AU ~= 500ls. Not only is the scale nice for human arithmetic, but it serves a dual purpose of also telling you the light delay.

Lightnanoseconds are a useful measure in everyday life as well. A lightnanosecond is about 30cm, or 1 foot.
