Thank you, Iridium, I realized I was grasping at straws. The RPi4 is such an elegant box with so much in so little space that I'd love to make do what I want. I fear that eventually I will need to make my peace with Kodi v18 but it seems to have removed more that I liked than it added to Kodi. I still use Confluence so you can see where I'm at.
I have a RPi1+ and RPi3b and a RPi4b. Only the latter will play 4K so it would depend on which TV I would be using it on. In 90% of my uses (hotel rooms, a friends house, etc) the RPi3b is very adequate. Even the old RPi1+ works for playing off a USB drive very nicely at 1080p.
Thanks again for your advice. You guys here are the best
