Best practice is 2" foam on walls, tape seams well. Cut foam sheets for rim joists and seal well with spray foam.
Standard 2x4 walls are preferred for framing as it allows room for electrical and plumbing and gives you something solid to attach shelves, tv's, etc to.
Bottom plate needs to be pressure treated and even better is to add a sill gasket underneath.
