I didn't actually get the database to build yesterday. There were a bunch of errors, from issues with my Apple Silicon Mac, to version issues with the Neo4j SDK, to memory sizing issues with Docker.
After a lot of fiddling, I finally got a Docker container to start building the database. It's been cranking away for a few hours now (hopefully it doesn't crash again).
A fun thing: I downloaded the entirety of English Wikipedia to my laptop. It's just under 90GB (which is honestly way less than I was expecting).
