Discussion on: I tested every link preview meta tag on every social media and messaging app — so you don't have to! It was super boring!

It depends on the implementation on (outlook or whatever) side.
What's behind that is usually a crawler of the company that read those meta tags to build a preview or simply take some excerpt from the content (i.e. first image available plus first 200 characters of text).

Usually yes, those meta are the better way to proceed. Otherwise the preview will show some introduction words instead a good description written explicitly for that.
The same way it would show a random image, not necessarily optimized for the format and not necessarily the one intended to be in the preview.

That's why OpenGraph or other meta tag formats appear 😁
