I would look at Pelican or Nanuk, both make excellent hard plastics cases. Watch for promotions or sales. I like Zargas case but they will dent, if that look is appealing go for it.
Being honest I really do not like hard case for anything that might get heavy, due to an issue I had many years ago. In the beginning my pro career sometimes there was no budget for an assistant to fly with me on international flights. So at the time pretty much all of my travel gear was in hard cases, struggling with the cases, I hit myself in the ankle. It took weeks for it to heal. After that trip I only use hard case for smaller stuff like a drone or some lenses that goes into a soft shipping case like a Tenba or Liteware. Those case are great protect better than the hard case and is easier on you. . If you are just talking some cameras and lens I would look at some of the rolling airport style case from Tenba, Think Tank, Lowe Pro and Peak design. Some of those also turn into backpacks.
I now carry all my cameras and lenses in a soft sided case from Think Tank, that sadly is no longer made, but it holds two A7 bodies and 3 zooms and 6 primes, only 200-600 has to have its own bag
