My thing is more "unwieldy hand-wires that don't really need to exist." For you though, the simple answer is a wireless "Alice" from Keychron. They have a few variations going from about $100-$200, a little less if you can live with a wire. Beyond that, you can look for Ergodox or go smaller to Corne. You end up with a lot of DIY or even commissions in that space, though, as it's sort of by definition going to attract people looking for something personalized.

You could be in luck, though: while none are much of a hub, the most active keeb community on Lemmy is probably the !ergomechkeyboards@lemmy.world one.
