Being quite absent-minded, I rely heavily on bags to keep organized and prevent myself from losing gear. I try to have a bag or case for every kit so if there is an empty bag, I know I've forgotten to keep thet piece of equipment.
I transport all my gear on a small scooter, so my bags have to fit onto passenger seat and the tiny foot rest of my Aprilia.
The bag that has served me the best was a 150 liter Osprey Space Station. But they don't make them anymore and mine is close to 8 year old and very abused.

The Osprey is great for getting gear to a location and the aluminum frame allows me to latch carbiners on a few more camera bags.
But on industrial shoots, it's not practical to climb stairs with the Osprey. So if I've not recced a location, I usually play safe and carry the Cressi diver bag.
Most items will fit in the main compartment, but micro dolly and my video tripod will have to be stuffed into the side pockets.
Things to consider while packing:
1. Is the bag full enough?
Ancient chinese junk boats are compartmentalized so that each compartment can be packed so tightly that the fragile porcelain wares cannot bang against anything on the rough seas because every piece is squeezed tightly against other pieces.
The more tightly packed your bag is, the lesser their contents will jiggle around inside.
2. Pack like an eskimo.
Because of the extreme cold conditions, eskimo hunters try to conserve energy by carrying as little gear as possible.
After each successful outing, they will leave out items from their kit that did not contribute to their hunt.
For lone shooters, the most obvious items to scrutinize is the casing that your gear shipped in. Eg. Does a lavalier mic really have to be protected in a watertight pelican case?
3. 'Pour' your gear (like water) into your bag
Water finds its way into every crevice. As far as possible allow you equipment to be 'fluid' inside your bag. I don't mean randomly dumping everything unprotected inside a large bag but rather understanding how gravity will affect the contents of your bag as you move it around. Use soft yielding material like neoprene, gel or ciesta padded cases to store individual kit so that each case can deform slightly when you pack more and more. The content in soft cases have some leeway to accommodate the content in another soft case. This slipping and sliding is more space-efficient than using hard casing where a large portion of the volume is occupied by protective foam rather than gear. Reserve the pelican cases for only the most brittle objects like bulbs, teleprompters, LCD screens.
4. Let the weak sit on the strong.
Plastics are more fragile than aluminum which in turn is softer than steel.Pack in a way so that the weight of the fragile gear rests on the heavier, tougher ones.
5. Pressure is force per unit area.
Pointed or thin-edged objects are the most destructive to other pieces of equipment Examine each piece of gear to identify sharp edges and points. Bag these items in velvet pouches or give them their own compartments.
6. Opt for semi-hard over hard casing.
Some items like laptops, mixers, EVFs can survive slight squishing. Smiggle-style semi-hardcase material like this one is good enough if you are not going to plonk heavy stuff on them
7. Hands are for emergencies.
Consolidate your gear into bags you can carry easily yet leave at least one hand free.
8. Pull it for security
Absurd as it sounds, the same security guard will bar you from using the passenger lift if you push your wheeled luggage in front of you but allow you to use the lift if you pull the same luggage behind you!
