Yoast is great but it only goes so far with structured data. There are many types of data that can be marked up and in fact schema.org, which provides (https://schema.org/docs/full.html) the specification, has over 600 different data types. Currently Google recognises about 30 of these data types.
For the full list see the Google Search Gallery which recognises common types of data that people search for such as Products, Reviews, Recipes, FAQs and How-tos.
At the time of writing this post, the number one result for the search "Structured Data for SEO" is a Moz.com article from 2017 which also has featured snippet status as well. Their article is a great example of content that can be marked up using the FAQPage data type - questions with answers. It's ironic that they haven't marked up this page with the schema FAQPage data type definition. To be fair, the FAQPage structure only came out in 2018 but that doesn't stop you going back and editing your posts.
