Most used 3D model/scene repo for staging

Dear fellow artists,

Is there a repository of 3D scenes to use for virtual staging? I see that some artists have exhaustive portfolios like this https://template.3dvirtualfurniture.com/living-room and worktime employee monitoring software. But it might be highly time consuming to build it all from scratch. Is there a  subscription service like https://www.poliigon.com/ for staging scenes?

Think3D has a good blogpost about all free 3d-model repositories. Here it is:
