Id second this. Checks all the boxes - Embeddable (yup i use sqlite) - fast - Open source - uses Cypher and not some obscure custom language.

You may have to do a lil bit of work to get backups working. But once you get past that, it's awesome.

I think its a no brainer for anyone excited by tools like duckdb and libsql. Fits in my stack perfectly well.
