For rich link previews, OpenGraph[0] is much more often supported than JSON-LD.
For seo purpose, the kind of JSON-LD a search engine will support is very specific and limited. You are far better consulting the targetted search engine's documentation (Google[1], Bing[2]) and following that. Anything else is a waste of time.
Outside of search engines, again, without a specific purpose, JSON-LD is mostly useless. If you have a specific need that requires JSON-LD, go ahead and include the data you know will be useful. Including anything else is like shouting into the void.
IndieWeb[3] does use structured data but considers JSON-LD a DRY violation and uses Microformats[4] instead.
