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

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.
