a 5/8" square mesh made from plastic. I thought about stapling this
over the insulation to hold it in place, but I wonder how long it will
last. I guess I could use metal chicken wire (poultry mesh, if you're
PC), but wouldn't that interfere with radio and cell phone signals?

Either will work fine--I'd expect the plastic mesh, particularly if it
is fiber-reinforced, to last quite a while. The wire would, of course
be permanent.

It won't be significant for RF attenuation owing to the porosity.

I'd think a simpler and probably cheaper solution would be to simply use
some light wire on about 18-24" centers stretched across, however. I
don't think you need anything near a full areal coverage to do the job
adequately although it would, of course be certain.
