Not sure why you are trying to invent some difference between Guiding Thunder and Hiraishin that'd cause the chakra used for the former to be less than what it is for the latter, but there's literally no evidence for that. Edo Tensei means Minato can use up almost all of his chakra and not feel the effects. We've already seen what warping Kurama did to him. Him being able to teleport SS during a battle is nonsense.
Not sure why you even mentioned the barrier when it doesn't teleport stationary objects.
Then there's the fact that SS>>Juubi>>It's Bijuu Dama when it comes to size. Lmao. Not sure what you people are smoking.
Shows how much you know.
First of all SS isn't stationary, it ran towards Madara. If it doesn't go towards Minato, it's never gonna hit him.in fact the only reason it hit Madara is because he ran towards it. Secondly, when Minato teleported the Juubi tbb with space time barrier, it wasn't moving, go read the manga again. Killer bee had stopped it from moving. Doesn't matter if the target is stationary, the barrier instantaneously suctions the object. The barrier only needs to come into contact with the object before sucking it in.
The evidence is minatos own words, he has to build up the same amout of chakra proportionate to the object he's teleporting. With the barrier he does not, when he teleported Kurama's tbb, he just opened the barrier, he didn't need to build up chakra. Same with the Juubi tbb, all he does is open the barrier.
Minatos chakra capacity does not increase in Edo form, if teleporting the Juubi bomb was in anyway chakra taxing, he would have felt the effects, but he didn't. You saw the difference when he had to use standard FTG to teleport everyone in the alliance, and he used kurama chakra this time, yet he was still tired from that. Yet in base he was fine from the Juubi bomb. That's the difference between the barrier and FTG.

The size of SS and the Bomb are almost proportionate, it's just the hands sticking out of the back that make it look larger. The statue itself isn't nearly the size of the Bomb. It's just the hands. And lol, the tbb is bigger than the Juubi:
