Noglider said it all very well. And to answer your question the width of the rim makes no difference at all to the lacing or desireable spoke tension. And all the 105 stuff I've used over the years has help up and performed excellently. It's good solid performing stuff at a mainstream price point. You should not apoligise or think you're compromising by going with 105. From there you're just buying more bling, a "name" and shaving a few grams with no solid improvement in life span or performance. The only point would be that higher end rear freehubs MAY have a slightly better weather seal on the freehub to wheel hub joint.
