I am using sqlite where a simple persistence layer is needed, both as the sole in the project or along with a full-fledged database. There are many such projects, once you realize that a database is just an abstraction; for example, for caching in a larger project, or to store results for a subsection of the project. But of course also for smaller, standalone projects.

Also, take a look at ws4sqlite (https://germ.gitbook.io/ws4sqlite/) for a middle ground between SQLite (embedded) and rqlite/dqlite: it's "normal" sqlite addressable via web services. May be useful in some scenarios.
