Are there any specific type schema influences google search engine in a larger way?

We all know the purpose of using schema in our website  and it helps google to understand better context about your website pages.

Recently , I was in interviewed for the SEO specialist role and the interviewer raised me a question like

Which type of schema can add more value to google search engine?

Based on my understanding,  I don't use specific schema that can help google to priortize our result in SERP. I do Implement schema type  based on the content relevancy. I shared the same answers to him.

Is my understanding to this process was right? if not,Then please help with your explanation
