Perhaps you could rent rugs from a staging company rather than purchasing items you'll just need to dispose of.

I cannot rent rugs from my stager as she has a no pet rule (of which I have 3).

Ah! Then personally, I would find something that complements the surroundings but costs as little as possible. Prospective buyers are buying the house not the furniture and ideally, will be busy imagining their own belongings in the space.

thank you!

Sisal can be expensive, but if you purchase ready made it can be very cost effective. It's neutral, (goes with everything) but is actually very elegant in my opinion. You could even have the rugs cut down and re-bound for your new home. Good luck on selling and congratulations on new beginnings!
