Hand powered drain auger. This isn’t exactly a quality of life enhancer but it’s one that new homeowners probably won’t buy right away. It is one of those items where you pray you’ll never need it and thank whatever deity you want that you do when you do.
Other enhancers: automatic occupancy light switches if appropriate for your home setup. We have them on garage stairs for safety reasons so we dont have to reach for switches while carrying things.
Good task lighting. I have a second switch in the garage for high output lighting when I need it to be bright as daylight inside while working on the car etc. And bright under counter lighting in the kitchen for cooking or entertaining.
