I'd suggest an American made two post asymetrical. Here's a pic of the Mohawk A-7 I just had installed in my garage. You can clearly see the electrical hookup. Its 220.
With that size shop I would highly recommend a 4 post lift with optional caster wheels so you can move it around the shop as needed and even out doors if needed. A typical 4 post lift runs on 110 so you could run an extension cord as needed. A 4 post does not need to be permanently anchored and will work on any floor that will support the vehicle weight. My 4 post is not anchored and it survived a 6.8 earthquake here in VA a few years back with no ill effects to the lift or to Dust Off which was 6ft in the air at the time the quake struck. There are pros and cons to both styles of lift so take some time to decide which will work for your situation.

Drop 220/240V from the ceiling on the passenger side - usually the controls are on the passenger side. So that's the shortest route - but you can always come across the top with power if the wall is on the driver side.
You have enough ceiling height for a nice two post asymmetrical lift. Don't cheap out here like I did the first time around. A lift is like the greatest tool EVER in your shop. You'll be shocked how much it's used.
