Open Graph
This page has a matrix of the different sets of meta tags and on which sites/apps those will display as part of a link preview (social card). There is quite a bit of mismatch between all of these. If you wanted to go with a single spec, it looks like Open Graph has the most comprehensive coverage across major apps.
