To go on with the modeling part, you should ask yourself a question:
1. is that an archviz?
2. is that a product viz?
3. is that a casual-like scene?
If 1 -> try to make the ROOM more interesting, and the furniture will come in a second time. Model internal stairs, cool counterceilings, hidden lights, play with architectural materials
If 2 -> focus on ONE ELEMENT (the sofa, or another prop at your choice) and blur the rest with shallow DOF
If 3 -> put mess in the room, everything you like (good models obviously, but I don't have to tell ya

That is my workflow. I always find me stuck as you are now every time.
