I think my issue was I was building it on a debian 11 bullseye. I managed to get all the individual pieces built and running, there was just one piece missing and I can’t remember which now. I’ll certainly give it a go. Someone just sent me a kvm build of debian sid just for that reason in fact! I believe they are working on the gvm debian package.
You can import CSV files directly into an SQLite database. Then you are free to do whatever sql searches or manipulations you want. Python and golang both have great SQLite libraries from personal experience, but I’d be surprised if there is any language that doesn’t have a decent one.
If you are running Linux most distros have an SQLite gui browser in the repos that is pretty powerful.
