Best place to utilize the jack

I use both a floor jack and a scissor depending on where and what I am raising the car for.
As mentioned already 2 of the floor jack pad raised edges get set between the oil pan and rear edge of the K if jacking the front, and if jacking the back with the floor jack it's always under the center of the axle.
I don't like lifting one corner of the car if it can be avoided.
I keep the original jack and a scissor in the car in case of a flat tire, so the bumper jack can do most of the lifting and the scissor under the A arm or one side of the axle gets that one tire up.

One of the last times I took my car to a tire shop I went down the block for a few minutes and when I came back they had the right rear wheel about a foot off the ground and the left front wheel was buried up inside the fender.
That pissed me off a bit and I told the guy that torsion bar suspended cars should NEVER have one corner lifted like that unless there was no other choice.
(Either barely off the ground on one side or that whole end of the car up by jacking in the center)

In my case if I jack up only one side I use the point where my 2x3 welded frame connectors tie into the torsion bars crossmember, or back where they tie into the rear subframe.

Speaking of not trusting anyone, I just got a brand new set of 18x9.5 rear and 17x8 front aluminum spoke rims with Nitto 245 and 225/40 tires and put them on the rims on the kitchen table.:D
Then drove them up to the tire shop and had them balanced and took them back home to put them on the car.

Some of the shops around here want you to hand them your keys so who knows who will pull your car in and out. NO WAY thank you.
If I can't trust them with the rims, why would I trust them with the whole car?
