No -

I'd prefer something I can screw and cable clip to.

A steel enclosure with a sheet of ply mounted inside?

Most people would probably just use ply. I was wondering what I could do
for minimal extra effort to give it a bit of belt and braces

The fire retardant ply you mentioned seems to limit the surface spread
of flame, rather than being completely fire proof. So lining with
plasterboard is probably better, as well as most likely cheaper, perhaps
with an ordinary ply or MDF sheet at the back as a mounting board. For a
one hour fire wall in one of my factories, we had to use two layers of
12mm plasterboard, with the joints not aligned. The doors might be a
problem unless you make those from metal.
