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.
See my lift light post here for lighting ideas.
