The main thing I would warn against, is walls that built as composites. Structural just dont care about insulation, ply, and anything thats not bearing load, so in some cases instead of modelling your wall with composite layers of brick/gap/block/insulation/ply, break this up so it excludes the block, has a gap large enough to place the block, and place the block wall as a seperate piece, because later you will hand this over to structures and you dont want it all to be part of your composite, because this causes issues in documentation for the structures team (and will cause you problems for wall based families) and annoyingly yes this means placing openings twice...but again these get handed over with the walls later.
