Yeah, I reckon having a split of the frontend and the backend results in about half the complexity in each. If you have multiple frontends you can upgrade whatever the least important one is to see if there are any problems
I didn’t really answer your original question.
When I was using NUC’s I was using Linux mint which uses cinnamon by default as the window manager. Originally I changed it to use some really minimal window manager like twm, but then at some point it became practical to not use one at all and just run kodi directly on X.
If I was going back to a Linux frontend I’d probably evaluate libreELEC as it has alot of the sharp edges sorted out.
Aramoana here in New Zealand. It has a population in the low hundreds and it is famous for a horrible massacre in 1990. The cops here don’t usually have guns and in a little place like that there are often only a handful of police that are anywhere in the general region.
