Catalina has beautiful rugs but they are pricey because of their high quality and knot count. However, you can find good and long-lasting hand-knotted rugs at more affordable prices that will still look great and last for years on esalerugs, overstock.com and ebay. A larger rug will have a huge impact on the appearance of your living room, more than a small but finer rug. I recently purchased this one on ebay for a very reasonable price. Because of the large, simple tribal design the knot count is not that high, but if you buy another Persian-type rug it will be denser and I think you'll be satisfied with the quality. In my mind, when it comes to rugs go big or go home.

Here's my rough attempt at the quieter/calmer style you mentioned. You could consider doing a room size natural fiber rug and layer it with a more colorful area rug in the seating area. This one is from One Kings Lane but may be available elsewhere.

Here are some kind of similar ones Danny Gray https://www.allmodern.com/rugs/pdp/danny-grayivory-area-rug-mtna1779.htmlDanny  https://www.allmodern.com/rugs/pdp/roxanne-hand-knotted-wool-creambrown-area-rug-cstd6420.html
