Im pretty sure that we can easily define metrics to measure that and we had.
This cult of relativism really needs to stop.

That's also the reason today we have substantial ZERO innovations and capacity to produce new things.
The young will give you a well simulated part/assembly ready for first prototype, the ancient normally gives you small note and a drawing. Prototype the two: the younger one is generally far more complex to being build, costly and far less effective than the ancient one. And it's not a matter of experience, it's a matter of different way of thinking.
Today we spent enormous time in bureaucracy with ridiculous stuff from ITIL/Kanban to the last bit, we spent enormous time in detailed reasoning being on contrary incapable of see the big picture. That's why for instance in shipping company when a (rare) EU doctor (we have less reformed medicine studies than the USA) went in the USA local seafarers they put themselves in the queue for being visited by "real" doctors.
Home that's more clear.
There is a big difference between education/enrichment and entertainment and while some content creators might walk the line between them there is a pretty big split.
I would say pre-defining what is “valuable” is probably not the best approach because it too prone to selection bias, an instruction video on how to do nails to a beautician is far more useful than a video explaining correspondenant banking systems.
That said the content as a whole can be measured in terms of its impact on cognitive and emotional state and well being especially on large sample sizes.
We already know that social media voyeurism causes a lot emotional distress, we know that certain types of content can make you “dumber” at least in the short term.
And on a larger scale we can check the social and individual benefits for specific cases, e.g. how many individuals who watched a specific subeset of content turned their life to the better in say a period of 5 years.
