Raised beds should have 1/4" hardware cloth stapled onto the bottom in order to keep moles and mice out.
The beds should also be placed over a permeable weed barrier as well. Cardboard will only work for a few years at most, only worth it if you are NOT using cedar for the beds as you will need to redo after just a few seasons.
Edging just means things will look neat but not stop nasty things from entering/growing into the bed...
