Should I stay with the white coated hardboard

is it flat, or curved?

it's slightly curved.

I was going to suggest the 5mm T&G PVC ceiling panels, but I think I
wouldn't on a curved ceiling.

The Vee board sold for soffit replacements might work. Usually available
in 1' wide "planks" with T & G edges (the surface is patterned to look
like 3 boards). It will probably go round a shallow curve across the
width of the board. Easy and light to transport if you chop into
reasonable sections.
