Oof, I feel you OP. I started down this road back in February, and I thought I’d be set up by now, but I’m still learning some of the pieces for a project that’s almost exactly the same as yours. If it’s any consolation, I have made a ton of progress. The hardest part can often be when you’ve chosen the pieces you want to use for your project, and then a kind stranger who means well adds extra complexity above and beyond what you want or need on top of their suggestion.
