Just write in Rust, it's easier to build good software than either of these languages (yea, yea, do you data analyst stuff in python until you start using POLARS). At this point it's a far superior ecosystem from a developer experience point of view and the fact it's going to get you as close to efficient as possible without you thinking too far into it is a welcome side effect.
