I use (Endurax Extra Large Camera bag) for travel with all my equipment. BeschoiIt is just perfect size for a regular day of shooting it is perfectly designed to fit everything that is necessary and feels comfortable, and when hiking trails, walking around the city,
As you see for the test I did pack more than can carry
1) Canon 5d Mark IV with 24-105 Lens
2) Canon Speedlite 470EX-AI
3) Canon 28-300mm lens
4) Canon 16-35mm lens
5) Camera Grip
6) Remote trigger
7) Battery charger, memory pouch, other cable and small things in the packets
8) iPad Pro 12.9 (2019) with the case and pencil it was tight, but the zipper close with no problem
The total weight was 8,6 kg 19.0 lbs. plus 1.3 kg tripod bottle of water and you ready, I'm just not sure to do what because after 1 hr. you will be exhausted carrying over 10 Kg 24 lbs.

I don't think so that anybody needs a bigger Camera bag for carrying more equipment if you have a need for more gear and a bigger bag, I recommend to buy a golf cart with the bag :)
The only thing what I would like to see is to add the center chest strap to keep it more firm when walking
