Lift placement

[RdHuggr68]

I am just getting started on my shop and was wondering where to set a lift in it. It is 42x42 12'ceilings 2 overhead doors. Doors are 12x10 and 16x10, in the 12x10 I will keep my trailer which is 30' long and the rest will be open. I just want to rough in power for it for now so I was going to hardwire a so cord out of the ceiling and drop it down to it. Have no idea what lift I am going to purchase or when I am going to purchase it. Is the power hookup usually at the bottom or the top of the lifts? 120 or 240 volt? I want it out of the way so I don't have to work around it all the time. Thanks
