I have no sources to link for this. But from my experience options are mostly (if not always) left for the user to select.
Examples that spring to mind are delivery / gift options in checkouts, filters in multi-faceted websites and selection/options in e-commerce websites.
Think websites like Airbnb, they show you a default view based on the criteria you searched and then they offer you the chance to filter or add extra options if you are looking for something specific.
Think of shopping websites or even car dealerships. You get your base model car and then you can browse through the available options if you want to add something extra to your car.
In general it seems to be always better to let the user discover the content herself than selecting things expecting to know what the user wants.
Give them the option but don't think you know what they need.
Of course all of the above is quite experiential I have to admit and it highly depends on context. But ask yourself this, unless it's a matter of "high importance" (e.g government / tax / health website) why are you selecting options for the user? And if you think it's mandatory to have (which is usually the reason you have preselected things) why are you giving them the option to unselect it?
