What style of rug are you considering?

I want rectangle. My goal is to give the house a clean minimalist look.

Pattern? Plain?

Given your minimalist desire but also the impact of your art in regards to its graphic design, consider combining simple and geometric.

Love the black and white. Perfect for this room

I love gabbeh rugs. Their simple design works with modern design yet also have classic appeal. I just bought an inexpensive silver grey one for my dining room. I went cheaper because of kids and cats but it cleans beautifully. First dibs has some stunning ones. I have shown silver rugs but they come in many other colors too.

This is homedepot for less expensive options

And from amazon for even less.

Many of these Chris Love Julia rugs from Loloi are on sale

An off-white background rug with some touches of black to anchor the room.

Since most furniture are dark, I would go with bright existing colors rug

or neutral/natural one
