Out of the box Django offers: authentication, database management and migration, a web server, a template engine, URL routing, and probably more - pretty much everything an app needs in a single framework.
Django also has some GIS tools builtin if you need to do anything with geographic data. It has a solid library of error handling, messages, and web security tooling you will probably need, and, the third party ecosystem, both Djano specific modules and the wider Python ecosystem are very powerful.
