It’s a big couch so make sure your rug and coffee table are both a suitable size! That’s crucial in making it look pleasing. (You can google “what size rug do I need?” and “what size coffee table do I need?” — there are some GREAT blog posts out there that are so informative and clear.)
Don’t worry about the rugs being too matchy. As long as they’re both in neutral families (blacks, greys, beiges, browns, whites), you can and should go with differing patterns. Stuff like this is a neutral.
Amazon has a great feature where you can see what the rug will look like in your room. Try a lot, and go outside of your comfort zone. Texture and pattern is important.
