Just an opinion which I know is not super valuable but categories won't help with most sites. Anything that permits user contributed content can become any rating at any minute unless all content would require approval by a moderator before anyone could see it. A few forums support that concept but it requires a proportionate number of moderators or I suppose a very accurate and reliable AI moderator if that is even a thing. I think it's easier and probably legally safer to just tag anything that is not guaranteed to be 100% child safe at all times as adult and let parents decide if they with to approve-list the site in parental controls.
