I did find ZMK, thanks! It seems though that - you have to go buy a board and a shield and put stuff together yourself - at least that's how it looked to me.
There's definitely pre-built options out there. On the QMK side you have stuff like the Technik, Keychron, Moonlander, and a lot more. On the ZMK side there's a few options right now but there's some in the pipeline like the new Kinesis 360 "pro" model.
There's also a lot of small companies offering build/modification services if you're not comfortable with a soldering iron but want something more exotic. It's usually not cheap but keyboards are honestly a really expensive hobby.
Thanks! I'll keep looking. I'm not uncomfortable with a soldering iron... but it's just not where I want to spend my time and mental energy these days. I see they're going to be expensive, and that's OK for me. I plan to get one good tool, not start a collection.
