While I'm fine with using SQLite for these things, I would counter that a docker-compose file makes using a db with your app roughly as easy as a sqlite file, only in that you'd have have a data directory as a volume mount for the db. PostgreSQL and MySQL/MariaDB in particular are pretty easy to launch with a configured user/pass for the db/app specifically with docker/compose.
If you're comparing to SQLite, sure... if you're comparing to installing and configuring an RDBMS server on a host OS for development work, I'm going to hard disagree. Most services already have a hosted docker container configured, usually by the developers of said service. Getting that running is often as simple as googling "service-name docker-compose example" and "docker compose up".
And once you do understand docker-compose, it becomes second nature. I'd be willing to state that dealing with a merge conflict with source control is more difficult than docker-compose.
