There isn't really a standard, and I suppose there couldn't be really.
Most folks who care about CW think you should CW news. But they don't really mean lighthearted stuff, they mean what I call "doom". (Lots of us don't want to be surprised by, eg, another headline about how the PM is planning a new torture chamber for refugees.)
I happen to think you should say upfront what you will CW in your profile. But, new idea.
