So, what if I use the largest hose, 5/8ths, on everything.

There's more to the flexible connectors than just the fittings on each
end, there's the diameter and length of the flexible connector itself.

Each flexible connector should have on it a rating in BTU/hr. That is
the maximum demand appliance that connector is good for. So just make
sure that exceeds the input rating of your appliance. As long as that
is true, the size and details of the fittings on each end don't really
matter.
