A question for you experienced people:
will the presence of a metal faceplate in the enclosure affect the wireless reception quality or range?

I'm considering using a brass, aluminium or steel plate that is laser cut to mount the TFT screen of an RX+ neatly in a wooden box, but hesitating before I spend the cash getting it made. I suppose I could experiment by placing some metal plates (cake tin lid etc) nearby and seeing what happens to TX->RX+ reception statistics, but would be great if anyone has some prior experience.

Unfortunately this question is non trivial. Because it depends boundary conditions how the signal will be. In principle everything can happen  …
This is the reason I made this housing out of wood and I want to put a little aluminium faceplate around the display.

As Werk said, the housing of Jarekh3 is very great and I think in sight of radio transmission it is the best solution, but I can understand why you want to use other materials, since I'm also fan of wood or metal.
Another possibility would be to use some plastics like this:
