Don't waste your money on different hoses for the front. The outside diameter of the hose is not an indicator of its ability to supply "clamping force". You only need to replace them if they are split/damaged/kinked/leaking etc..

The ID of the hose will determine the amount of fluid the hose will flow. I doubt that the different size hoses would flow such a substantially different amount that you could notice anything from side to side or front to rear.

Smaller ID of the hose will NOT increase the pressure at the caliper.

A smaller bore master cylinder will increase the pressure at the slave/caliper/wheel cylinder, compared to a larger bore master at the expense of volume of fluid displaced.

If your brakes are still "spongy", there is still air in the system somewhere.
