I used to have similar issues with the Moonlander. This is how I solved them:
> coding is a lot more painful or difficult to get used to
Primarily, it was the symbols, {}()[]$ etc, which were hardest to hit for me. I put my Layer 1 "hold" key to the left of my H key (I use the QWERTY layout) and have remapped keys under my left hand to output symbols with Layer 1. It takes some memorizing to remember which key to press for each symbol, but it is not too bad.
> I use the arrow keys, which are in awkward positions on the Moonlander
I used to use the arrow keys using my middle and index finger. Now I use my thumbs. It's a lot easier this way.
> finger combo seems weird
Try remapping those modifier keys to an easier-to-reach key, or alternatively setting up a macro key (for example, I have a Command-space macro key because command and space are on the same thumb cluster in my layout).
