An item on the home page, FAQ, or Favourites list?
I can see where you are coming from, though it’s not an issue any user / visitor has ever raised with me in over 10 years of PGV/webtrees/kiwitrees use. I’ve always assumed they are generally just OK with whatever they get as a starting point and assuming as it’s my site I have my only logic for the choice.
But yes, those are all valid options to describe your choice of default individual. Personally I would probably go for a combination: a favourites block included inside an HTML block with descriptive text.
