Hi yemafu and welcome to WebmasterWorld [webmasterworld.com]

Which schema options you should use is something you would need to decide for yourself. If you leave the Yoast settings at their defaults (webpage+article) then that is the context Google will use to evaluate your content. In the Yoast plugin's UI you can see your options on the Schema Tab and decide which "page type" and "article type" would best fit your content.

It sounds like you are not familiar with your options so you can make your own decisions. You can read up on Schema at their community: [schema.org...]
Or you can read more about using the schema settings in Yoast: [yoast.com...]
