Polars' support for SQL is pretty nascent and missing a lot of functionality. If it were better, we'd use it internally in Ibis for the Polars backend implementation. If you're going down the mixed SQL, DataFrame API route then Ibis is probably the best solution out there for that. I work on Ibis, so take what I say with a grain of salt. There may yet be other libraries out that there that have similar functionality.
