It took a full month but I finally took the time to create all (well, most of) the sliders, buttons, etc that were needed to make the custom settings menu I had been waiting to create. It still needs work and polishing and fixes but now you can create custom board sizes, starting colors and other settings. The plan is - if I have enough time - I can expand the settings menu to be robust enough that I can just start using that or an equivalent scriptableobject to create scenes and "levels". It involves a lot of work and refactoring and UI design though, and unfortunately moving countries and looking for work takes up a lot of time I'd otherwise spend on that.
