First Cruise: buffet?

I’ll be doing my first cruise soon (I’ve done a couple of Viking River cruises and many, many Navy submarine cruises, but never an ocean cruise). I’m not super interested in all the food options, so the buffet seems to be the simplest most efficient choice. But all we hear about is norovirus and other risks associated with buffets. Of course I will be washing my hands frequently and doing all the important things to prevent anything, but is it really that big of a worry? I’ll be on the NCL Getaway, and from everything I’ve seen and read, the buffet seems reasonably safe, but is it? Appreciate all insights!
