WordPress on its own is not capable of scoring great page speed scores. Even with the best development approach, the additional weight that is carried from the backend to the front-end with elements such as themes and plugins will always result in a slower site. By optimizing the site and utilizing additional services, such as caching with Cloudflare, efficient hosting with providers like WP Engine, and using services like WP Rocket or NitroPack, you can improve page speeds.
