When you move out of the previous place, pack in order. Stuff we need now, stuff we need this quarter, stuff we might not need for a year. Then don’t unpack.
So when you finally work out what you want, after you’ve been in two months you’ll have only moved into part of the house properly.
Then you can do all the stuff already mentioned without having to almost completely move out.
We had three different master bedrooms and two living rooms in the first 6 months of living in this place. Some of them were even the same room. (one of them technically wasn’t a master bedroom, it was a room with a mattress on the floor and clothes piled up in the corner.)
Was all better than trying to pack stuff you haven’t actually used since unpacking back into a load of packing boxes you’ve just thrown away.
