Progress report - the screen is installed but there are a couple of problems. After the phone boots up the screen immediately goes blank, both on the factory-installed Manjaro and Mobian on an SD card. Seeing a recent thread on that topic it appears that the problem is the proximity sensor which I did not realize had to be transferred from the old screen housing. I moved it over, including the little rubber gasket, but unfortunately the problem remains.
The other issue is that I managed to damage the buzzer, which is attached to the USB-C side board. When prying that out of the old screen it is all too easy to pry it apart. That part is currently out of stock in the store, however it's not critical to the phone's operation.
I'll have to take another look at that proximity sensor. I'm getting very good at taking this thing apart...
EDIT: I took the phone apart again and checked that the proximity sensor and rubber gasket were seated OK and pulled the contacts up a little for a better connection. At least I think that's the proximity sensor, I found a diagram that said it was the "Reciver" but the user manual seems to say it's the speaker? It's a small rectangular piece with spring-loaded contacts on the back. A diagram calling out what everything is would be really helpful. Closest I could find is this, and Item #5 is what I'm looking at, with #4 being (I think) the rubber gasket:

Anyhow, I currently have the same problem, screen fades out after a few seconds. I also took a look with a magnifying glass and can see that when I accidentally pried the buzzer apart that a connection on a solder pad broke. That can wait until I can get another USB-C sideboard, the screen problem is what is making the phone unusable.
