Yes, take all you can get. Either your wife can take it as a business deduction or her company is paying for it. There is no such thing as too much speed.
Then, the only real way to know what you'll get is go knock on the doors of the house on either side of what you're looking at and across the street to see what they're getting.
As stated, fiber to the curb is fastest, but I got fooled on this once. The provider sent the service via radio or microwave for a long distance, but they installed fiber in the subdivision because long term is was the most cost effective for someday when they'd replace the radio link with fiber. Needless to say, our speeds weren't the best.
