is this the best choice for outside mosaic in a temperate climate (40 deg-80 deg F)

I would suggest an adhesive that is not water based as well. Silicone adhesives are waterproof, and would withstand the outdoor use better. Use a grout sealer that is intended to prevent absorption and permanent staining to keep your mosaics looking fantastic.

For sculpture project, will this bond large sheets of cardboard together?

Yes, you can bond large sheets of cardboard together.

Is this food safe? I would like to use it to seal terracotta pots that we will be growing herbs in.

I would say yes.. it is basically a strong water souluable elmers type glue. I would use it on terra cotta pots.

Can i mix this with premixed grout to make it stick better to a wall -a vertical surface? If so, should i mix it or just put a layer on the wall first

You should not mix the glue with grout. If you are putting heavy tile on a wall you would use Thinset which is available in different strengths for walls.
