Polycarbonate is optically clear, by far the strongest option, but also

strength and price.

Not come across PETg before... do you have a source for it?

I would be surprised if you haven't come across it; it is the stuff plastic
drinks bottles are usually made from. I came across it as a material for
vacuum forming clear rigid packaging. I didn't go ahead with the project,
but ended up with a few flat sheets, which came in quite useful when making
some splash guards. It bends quite well with a hot air gun. I presume most
plastic material suppliers could source it.
