I've usually seen "thumb clusters" used for those style of key layouts, rather than thumb pads.

I've been using some variant of the Kinesis Advantage line for over 10 years - currently the Advantage360, their split board. I used an ergodox for a few years before that.

The Advantages are all 3d curved layouts with thumb clusters like the Maltron, and I haven't had RSI issues since making the move. The 360pro runs ZMK for firmware customization, and the stands do support different tenting angles.

Worth a try if you're looking for a more direct alternative to the Maltron.
