60 g cube - plumbing question

I have a mag 9 pump with 3/4 ID outlets.

I also have a Sea Swirl (3/4)

From the pump should I do

3/4" to 1" coupler with 1" tubing to the sea swirl (with another 1" to 3/4" coupler)

I have 2 outlets, will be using 3/4" loc line.

Is there any advantage to using 1" tubing up to where I reduce it to 3/4 for outlet and at the pump?

I already have a ton of 3/4" black vinyl tubing lying around I was going to reuse (never been used, meant for aquarium use). I did the head loss calculator and I would be around 550gph using 3/4" tubing all around. Would 1" tubing from the pump up make any real difference?

I am keeping softies. Never had a ton of flow and everything thrives in my current tank (just going to a cube w/ overflow, etc)

For starters the output of the mag-9 needs to be doubled to obtain max flow. I would atleast go to 1" on the output.
