Seeking wisdom from those who have installed a lift

There is little to no safety issue with a 4 post. Unless you roll it off the end, but there are plates on the front, and back has plates or ramps serve as stops if they are hinged.
Nearly impossible to damage a vehicle in a 4 post, but something you need to be aware of with a 2 post. Bent rockers, floors, fender bottoms, one instance where a garage did a safety on a 67 mustang and the tech bent the torque boxes. Not all cars are well suited for 2 post lifts.
Not to mention the two 2 foot by 19 foot long work benches to pile tools and parts on. I never have to set wheels on floor and lift them back up to mount. Stand em up and roll into place.
Sure makes my life easier, and my impact doesent ever fall to the floor now.

it raises vehicles 7” off the floor, so extra height makes underhood work on taller vehicles a challenge sometimes.
And clearance for shop crane to pull engines adds more height. Unless its an open front hoist. Those are really the ticket.
