It doesn’t matter what model home you have, it can be any home. Tile and wood floors are the best and the most expensive. Carpet in bedrooms is fine if you like warmth on your feet. If you want to go cheaper, you can get vinyl flooring and put it right over existing wood floors and it will look fine.
As for echoing, you’ll need some type of carpet or acoustic wall treatment to deaden the sound. I’m an audiophile and I use acoustic panels in my audio room to treat any echoing.
Use large area rugs with anti-slip padding, and I mean large like 8x10 or larger in each large area and it will make a difference
