It looks like Laravel Jetstream is the best option for a headless CMS for Laravel 10. Jetstream provides a great starting point for building a Laravel application with a modern, reactive frontend using Tailwind CSS and Vue.js. It also includes authentication scaffolding, API support via Laravel Sanctum, two-factor authentication, media library, and more.

If you're looking for something more lightweight, you could also try Laravel Breeze. Breeze provides a simple starting point for building a Laravel application with authentication, registration, and password reset. You can find more information about Breeze here: https://laravel.com/docs/7.x/breeze.
