I looked into how to perform sorting and pagination with Strapi v4’s GraphQL. Documentation was found at the following location.

https://docs.strapi.io/dev-docs/api/graphql

Specifically, pagination and sorting could be performed by writing queries like the following.

query {
  blogPosts(pagination: {page: 1, pageSize: 10}, sort: "createdAt:desc") {
    meta {
      pagination {
        total
      }
    }
    data {
      id
      attributes {
        createdAt
      }
    }
  }
}

I hope this serves as a helpful reference.
