I thought you weren't supposed to use exterior grade paints indoors due

thats right, and yes its an enclosed space. Some types such as water
based would be ok, but some would be too toxic.

Re breathability, asonry paints arent to any significant extent. They
pinhole, which is fashionably called 'microporous' but the degree of
damp evaporation ability is very low compared ot genuinly breathable
paints.

You'll probably be fine with unbreathables, but in some cases they do
cause damp build up and resulting problems. The lime paint mentioned
above is cheap, easy to apply and fully breathable.
