I'd have a look at DuckDB as well, looks like they're doing a great job with their useful, practical and successful innovation and a ton of interesting differentiating design decisions; I hear that's on top of SQLite, is that right? They must have a fair amount of code of their own regardless.

Then there's also some projects who have tried to port or re-create SQLite in Rust.
