Retrieval pipelines strip most markup before a model ever sees your page. Four schema types keep showing up in what engines quote anyway: Product, FAQPage, HowTo, and Article with a real author.
The quiet workhorse is Article authorship. Engines increasingly attach credibility to named people, and author markup is how they connect your page to a person with a footprint.
Markup does not make you quotable. It makes your quotable parts machine-liftable.
Ship those four types on the templates that answer questions. Spend the time you save writing better first paragraphs.
