Questions & a few problem statements while designing a 2-car garage

The garage will need to house a set of 5 MT tyres for the Thar

BHPian airguitar recently shared this with other enthusiasts.

I'm building a 2 car park at my home, which is 15'6" x 18'2". A picture is attached.

Constraints:

It is not a big space and I may have to park the cars with one facing the road and one facing the wall to ensure that the driver-side door of the cars open to the same side, therefore reducing the buffer space needed.

While the car park is open from the front(the builder won't allow a shutter), it's closed from above.

The garage will house a Mahindra Thar and a slightly longer car (for practical purposes, let's a Kodiaq).

There will be a third car, a compact EV parked in the driveway and will not compete with the other two cars for the parking.

Rats, frogs and therefore reptiles may be present in the open spaces nearby so I cannot afford to have anything on the floor, nor have anything unclosed - everything will need to be neatly shuttered in, as far as the storage area goes, as the garage itself doesn't have a shutter.

Problem Statement:

I'm a bare-minimum DIY guy: Changing tyres, cleaning my cars, extremely minor replacements of parts etc - that's as much as I do. I'm not an extreme DIY guy like some of you who do out-and-out overhauls of cars in your garages.

The garage will house a portable pressure washer (the tap outlet will be hidden behind the garage, but not very far from it 3-4 feet away)

Will house a 2-piston, 3-tonne hydraulic jack, largely for the Mahindra Thar. I was considering a mini hydraulic lift for the cars, but friend and fellow tbhpian @soumobakshi knocked some sense into my head into getting the 2 pistons hydraulic jack

Usual consumables and cleaning tools: dusters, wiping clothes, shampoo etc

The garage will also need to store a 3 pax camping equipment set (tent, boots, inflatable mattresses, leech socks blah blah)

Will house some electricals: a wall-mounted car charging point, some electrical panels (main electricity board, elevator panels etc)

The garage will need to house a set of 5 MT tyres for the Thar (let's assume the bigger sizes), they will be stored mounted (as in the encircled stack approach). The idea here is to build a heavy steel frame that will bear the weight of the 5 tyres + alloys and then be covered in a wooden frame with the steel frame bearing the weight.

Questions:

Is it a good idea to mount heavy stuff such as the jack, and spare tyres on the wall, irrespective of how strong the supporting frame is going to be? I'm a little finicky about putting anything on the ground as it will start housing rats, insects etc.

What are your thoughts about the tyre storage area, which is a tallish vertical part on the left of the storage cabinets? I will perhaps need to retrieve them only by standing on a ladder.

Any other important things that you would like to suggest that I'm not considering today but might miss or find inconvenient later?

What other tools/tooling do you think the garage should house?

Thanks for your time and input!
