Solid render is not for insulation, it is a hard shell that protects the insulation, aids waterproofing and improves the finish/aesthetics.
Yes, you are correct that the thicker dome has more thermal mass and be a better oven for long cooks, but insulation is very important as well which is why the 50mm perlite layer is a good addition.
No reason you can't render the brick arch if you prefer that look.
