A "we buy houses" company offered me cash in 7 days. How does that compare to listing with an agent?

A cash offer from a we-buy-houses company trades speed and certainty for a lower price, since that buyer builds in a resale profit and repair costs the way a house-flipping investor would, rather than pricing against competing buyer demand. Listing with an agent exposes the property to the open market and any competing offers, which typically nets more even after standard closing costs, though it takes longer and requires the home to be shown. Weighing that tradeoff against how much timeline flexibility you actually have is the real decision.
