You will not go wrong if you use the larger size cables for linking your batteries. I would recommend you use the higher rating to ensure minimal voltage drop as this will also ensure that each battery is charged at the same voltage and hence more likely last the same period of time.

It also minimises the risk that in case where the charger is not operational, that you have one more more batterys charging others in the bank.

In the case of the fuse, you should size it to cope with your expected load + a margin, so that should something go wrong it will will fail first.
