Welcome to iboats.

I would have each device on its own appropriate sized fuse.

Electronics are fused internally. There is no need to fuse externally other than convenience and to protect the wiring.

In this case, there is no reason (assuming the wire is adequately sized) why you couldn’t increase the size of the fuse and move one.
