I could never get used to ergonomic keyboards. I actually spend a considerable amount of my day typing single handed across the entire QWERTY so I don't have to remove my hand from the mouse. I developed the habit working on far too many apps with bad/missing keyboard shortcuts or broken tab ordering.
For me I wanted a smaller keyboard, but one that still included the numpad and ended up with this custom build:
I get that, I've practiced with my ergo board for like a year and still don't use it exclusively bc of one-handing stuff (though learning a new layout at the same time cert. didn't help).
There's a layout based on multi-key chords called Taipo that has this really interesting "reversable" property, in that each half is a mirrored copy of the other, so you can type any letter (or eg. tab or return) with either hand. I think that's super cool, but don't think chording is for me, so I'm trying to imagine what a compromise might look like.

I use a fullsize board at work, but at home I prefer the slightly smaller footprint that I got in that design.
