I am not a daze user myself, so I am not the best to be answering your post, but you would probably need a shop, and to get the items to fill it separately. You may have a better time with browsing the https://f95zone.to/forums/asset-releases.95/?prefix_id=33 but that has mostly bodies and toys, not sure about much else.
How familiar are you with importing non daz assets? I may be able to find some decent for plans, furniture, or make a floor plan with good lighting potential, but they will probably be .obj files and you may need to fix textures.
