I think you didn’t understand correctly what strapi is, its just a Headless CMS(offering acces to your data through RestAPI / Graphql). You can use any rendering framework that you want, React, Vue, even jquery, or even vanilla javascript, or PHP, that doesn’t matter how you will render your data, the only thing that strapi does is providing you the data. Think about it as a car engine, you can put that engine in any car body.
