Ed, we are dealing with the same question here. We decided 4800 x 3200 (same aspect ratio as full-frame cameras) for downloads in ZIP files
We also made a "Tour Size" where members can click through the shots one after the other and its only 900x600.
Much of the software used these days to view image sets has that "fit to screen" feature where it resizes the view (zoom out) automatically so if big images can be viewed edge to edge.
I see you said 1080p at 12000. We tested that a bunch about 18 months ago and only a few fans out of hundreds helping us test could tell the difference in mp4/h-265 files rendered at 12,500, 10,000 or 8500 max. I'm going with 9000 and no complaints (faster downloads, less bandwidth, and for lower power members on older systems, less means faster / smoother read from disk.
