I think there is a solid point just in front of the back wheel that may be ok to jack from , its near the torque tube. will your jack fit there?
the fairly small typical floor jacks go lower than most bottle jacks , thats what I use if the bottle jack wont fit. a small bottle jack is handy so either a small bottle jack or a floor jack might be helpful.
if you just take some 2x4s and cut them about 14" long, then lay two one way , two the other way , repeating and nailing each then you have a pretty solid block, I made several like that and find them very handy.
I still take another bottle jack and lift it up under the car taking just a tiny bit of weight, thts just insurance, I do not take chances with cars toppling onto me.
I recently got a pair of car ramps, haven't really used them , a neighbour put them out in the alley for grabs, they may be oK for some things. i suppose you can drive the car onto a pair of those and save a bit of work even if you are jacking.
if you have a firewood pile you might find you have some suitable pieces that are cut really square and are not going to split apart.
ive had it happen where I was pulling on a wrench and put my hand upon the rocker panel for support and the wind blew the door closed, I pulled my fingers back out but that was a bit scary as I could have been trapped. Murphy's law.
if you jack a car up so much that a second wheel lifts, be caereful thats where the car can move, and topple off the jack. it s possible for the car to then move foreward back or sideways.
I do it in steps , its more safe and if I mess up, if it did fall, it can only fall a couple inches.
if you put it withte tires o blocks , it may not hurt to nail down some ribs so the car isn't; able to roll forward or back and roll off the blocks.
Id suggest having a couple of wheel chalks
I have one that I like , it is hand made of thick round bar stock so when its against the wheel it is also under the tire so that way it can't push away
even on the level they can help assure the car is not going to roll.

i also keep piece of aluminum checkerplate that is fairly thick , I use that to put under my jacks as I'm working on gravel. if I travel far il oftn throw in my checkerplate and my floor jack , a bit heavy but easier to use than a factory jack.
i made a couple of fairly high adjustable jackstands. ( axle stands) I find those handy because they don't need a large area. I designed the ones I made in such a way that if they do push into dirt they become lodged by the support bars I put between each leg.
Mine are fairly stable. I've seen cheap ones I don't trust so much, I made mine extra heavy so they won't fail on me or rust out. Bedrail and heavy wall tubing holes and a pin to change the height.
generally I will try to jack the car in such a way I end up with my two axle stands under the jacking points and make sure they are secure so they can't go sliding off .
if you are working on wheels and brakes obviously you cant put blocks under the tires. if it's a muffler , that's different. If you work on an exhaust system, it can be important to have the car supported by its tires so its suspension is in a fairly normal compressed state.
if a car is stored maybe there is some benefit to getting it up off the ground, to be less prone to rusting from nearby wet ground. Let the air get under, up out of the dew. rather than it being trapped in boggy tall grass etc. that might reduce humidity.
long term maybe springs age and compress, the torque tube may be a different animal but cars can sag with age. a guy in a spring shop told me its that the springs get rust and the tiny unnoticeable cracks in the metal cause the spring to weaken with age and rust, then sag. i had them re manufacture ones for my old volvo, stock height but a little stiffer, but those are coils. it restored the height to original.
some suitable chunks of marine plywood may be handy to have around. spread weight or use them as shims or something to stiffen the ground up. a base for your bottle jack. normal plywood rots fast.
a scissors jack can easily be found at any auto wrecker, they do go very low and are inexpensive, one may be ok to get the car high enough for a bottle jack. be careful though , those things can topple easily.
a lot of the time a bit more jacking means less squeezing and contorting and the job can be a lot more comfortable.
getting dirt in your eye is always a hazard. I've done it so many times and still Ill forget my safety glasses and do it one more time. often in too much of a rush to go find them ..
