The mikefive is my dream work keyboard. It's two keys extra from what I have currently but I know I can find something to do with the extra cluster keys
less specifically like OP's, but a really great product that I and a bunch of my coworkers use: the 'Ultimate Hacking Keyboard' 60 (typically referred to as a UHK). I have mine with the palmrest and the recent riser accessory, so I use it split and tented for less wrist/forearm tension.
I wasn't sure how I would like the keycaps when I ordered it. Hard to describe but they feel better than the stock keycaps (with the silent switches) and sound a little better when I strike the plastic keycaps. The stock keycaps have a slight hollow sound (if I recall correctly).
Not sure if you're familiar with it, but Glove80 which the parent comment you were replying to is very similar to Kinesis boards (concave keywell, staggered columnar layout, etc.) but leverages a lot of the open source stuff like ZMK firmware that Kinesis doesn't support https://www.moergo.com/
Edit: nevermind, I just learned that the advantage360 pro uses ZMK as well. Either way, they both seem like great options for people who prioritize the ergonomics over aesthetics :)
For keyboards really similar to OP's

Corneish (out of stock): https://lowprokb.ca/products/corne-ish-zen?variant=376943319... Unicorne: https://new.boardsource.xyz/products/unicorne-LP
The corneish is an absolute gem in my opinion. It is possibly (probably?) open-sourced too.
