I don't know what policy is with the new terminal (T2) at MEX. There is a hotel on-site, but I don't think it's cheap. Fourteen hours is more than enough time to make it into the city. I'd check my bags or use a locker in the airport, and get a pre-paid cab into town. Hostal Catedral is quite cheap (I think dorms are $5-6 per night), and very central. An pre-paid cab will cost less than 150 ($10 at today's exchange) pesos from the airport to the hostel - you should be able to arrive shortly after 10pm. There are also budget hostels in Roma, Condesa, and Zona Rosa - all similarly-situated neighborhoods with respect to the airport. It would be a shame to spend Friday night at the airport.
If you're traveling without bags, you could even take the subway from the airport to the center for $0.15. Let me know if you're interested in specifics - I spend a lot of time in Mexico City.
