Two semi related points, but yes the CH is often sited first, and that is usually set by proximity to utilities. You see a lot of Ross courses with the clubhouse in the corner of the site, and usually nearest where the city was. He was frugal, and back then, many country clubs truly were in the country and had to consider where the utilities were closest. It is still true. I was co-designer on a course once (never built) and the consultant wanted to put the clubhouse on the east side for the best sun orientation, but the cost of running roads and utilities to that ideal site was going to triple the cost of the project, so it was quickly scotched.
Since 2000, some progressive land planners have gotten away from the ideas of putting the clubhouse on the most prominent hill on a residential golf community. The reasoning includes, 1) Saving those views for premium residential lots, and 2) It is often far less expensive to create clubhouse views from the clubhouse by landscaping the first few holes and/or range.
Architects may have gotten too set in their ways about running the 18th right at the clubhouse for the traditional finishing hole look. That is good for circulation in most cases, but it is sometimes possible to consider the old NGLA trick of sliding the 18th by the clubhouse, not running it right up to it. In modern golf, having a distant 18th green or 1st tee is okay, in that the associated travel time before and after the rounds aren't usually counted in the 4 hour pace of play equation. Those are both much better than having some long distance between two holes from 2-17.
