There is (at least) one company providing this kind of services. They tag in the movie all the content with timestamps, and can provide it to a player to skip or not depending on the tag (nudity, violence, etc.).

As far as I know, it was manual, but that was already a few years ago.

I don't remember the name of the company, but surely it can be found and there are probably multiple such providers. The service was provided to TV operators (satellite, cable or pay-TV) to include in their set-top boxes.

PS: of course, as sjcsjc mentioned in a sibling comment, it immediately gives the idea to many people to only show those parts :)

There was. The most well known was CleanFlicks. They were all sued into oblivion.

There's a documentary about it: https://m.imdb.com/title/tt1007026/

Hadn't seen that. Predictably, also being sued by multiple entities: http://blog.vidangel.com/category/legal/

Studios have the airplane edits of many movies.. not sure why they won't let you select that on the Netflixes.

My 14 yo would be very happy to select those versions.
