Cloudflare Pages is actively maintained and getting new features, it has a built in CI/CD Build Environment, preview builds, rollbacks, built in support for netlify like redirects and header changes, Git integration, etc. One of the biggest things might be the fact that it still uses KV under the hood like Worker Sites does, but you do not get billed for static asset requests. You only pay for Pages Functions requests, Functions are workers with a bit of extra stuff on top like file based routing, middleware, and more to allow you dynamic functionality, which is also versioned with the rest of your assets in each deployment.
