I would take a look at Laravel. It has built in auth{n,z} options and you can deploy it easily with Laravel Forge sass that can deploy to multiple cloud providers using boring MySQL, Postgres and redis. And you still retain control of your infrastructure on the cloud provider. You can also develop locally using laravel sail docker dev environment.
