Sounds great, except, and understanding I’m in a minority of 1 here, the touch screen. I’d love this tied to a menu if needed plus a 4X4 keypad or such. …

The costs aren't cheap compared to those display sizes (e.g., > $10 versus $34), but 5" at 800x480 is nothing to throw rocks at and is easier on the eyes for us old people. Also, quite a few have adopted the Nextion display and they cost twice as much as ours and are about half the size. Also, we give you an experimenters platform with a dozen empty pins and idle resources to play with (see feature set below). Also, we have a pretty robust feature set:
