Don't have any  pictures but I stayed at the southern most Island on the east end of the lake which would be directly on your route.  From what I recall, there was an open area on the site, up a short gravelly  hill.  The site faced east (and the prevailing winds) and I think swimming was fine. It was a long day getting  there and I likely didn't do much other than eat, go for a quick dip to clean off, and go to sleep but it struck me as a solid place to stay.  I was originally looking at the sites on the little peninsula just to the North but this site looked better (from the water  at least).

Another site I paddled by that looked good was the furthest west site of 3 on the island by the narrows from white trout.

Welcome!  I'd recommend balancing the use of the map (where you can see the topography and relative point of view with the PCI type resources on this site that you've consulted) to consider a few options and then doing the real decision-making on-site.

We often would have a few sites in mind and visit them in sequence - we get out, look around and talk about the positives and negatives.  Maybe the thunderbox is uncomfortably close to the firepit, maybe the fishing looks lousy out front or perhaps the views are obscured or limited...but it's a fun way to develop an appreciation for the variability from one site to the next.  

Sometimes your first site is a gem and checks all of your boxes...that must be the result of good, clean living because that doesn't happen to us so often!  ;-) Trippythings is spot on with the 'personal preference' part - one man's trash is another man's treasure!  I've been on the tiny island site in the easternmost arm as you are heading towards the Merchant portage and also on the peninsula site just southwest of that island.  I would say the peninsula site offered more of what you are looking for.  All four of those easternmost sites should have some degree of sunset view though but the tiny island won't check many of your boxes.  

Enjoy the trip!
