As someone who does not have fingers that angle to the left, I think perhaps even more important than the thumb cluster is having a columnar or ortholinear layout. I switched from a staggered QWERTY layout to a split, columnar layout similar to the Kenesis (ZSA Moonlander) with Dvorak, and I feel like the columnar aspect was probably the biggest improvement for my hand health. I also recommend moving control to the location commonly used for caps lock if you're specifically struggling with your pinky hitting control like the OP.
