As somebody who likes and uses clipless pedals, unless you have a particularly long or gnarly commute, it's probably not worth the hassle and expense. I started using them when I was competing and kind of got hooked. Some people claim that they are significantly faster with them. I find the speed improvement to be situational.

They are nice for some other reasons. I have not been doing many long distance rides as I have in years past. A week ago I did a 55 mile ride and by the end, climbs that normally wouldn't bother me were getting to be a challenge. Having clipless pedals allowed me to use a different set of muscles to help power up those hills.

My commute is only about 6 miles and there's no particular need for them on that, though I still use them frequently just out of preference. I would have never got them just for commuting though.

It's not that hard to learn to use them. Many people have the experience of forgetting to unclip while coming to a stop on one of their first rides. The result is often a slow motion, inelegant trip to the pavement. Other than that, learning is pretty uneventful.
