Questions about protecting my first project

This is my first (test) system to teach me about solar systems. I have questions and need help before I hook this up to loads. It's working but I'm not sure about protecting it.

1. What amp fuses do you recommend for A, B, C, D?
2. What T-Fuse would you recommend for E
3. Because there will be fuses in the Distributor Module do I really need fuses in the Power In Module which has the mod to hold fuses (but I change it back)
4. The circuit breakers close to the batteries are meant more for 'cut off switches' because I just had them. Would switches be better and put the CBs somewhere else?
5. What would you recommend between the MPPT and the Distributor Module?
5. Where else would you recommend fuses, switches, circuit breakers?

Thanks, this is a great learning experience.

Theoretically
1) 2/0 wire, 200A fuse for A; B 12V busbars you have to know 12VDC loads to know that; C if that’s 30A use ~35A and 8ga wire; D is whatever fuse Victron wants in the manual.
2) Answered for A above
3) follow Victron manual instructions
4) if F is 100A per battery I’d use 125A Class T not breakers. Or put the breakers as convenience shutoffs after the Class T’s which should be at the batteries
5) Answered for “C” in “1)” above
5.2) see “4)” above
