US had the clearest motive of all since destroying the pipelines meant not only that they could increase their control of the gas market and as you said, secure transshipment through Ukraine and Poland, but by doing so they also eliminated any possibility or pretense of Germany and Russia resuming their economic collaboration. The US had motives and plans to blow up Nordstream well before it happened. Biden said as such in Feb 2022 before Russia's SMO/invasion even began.
The bombing also forced Germany and the EU to deepen their dependency on the US and severely damaged German industry. Any benefits that accrued to Poland and Ukraine also accrued to the US. Also, US naval vessels were operating in the immediate area of the bombing, and were conducting underwater "training" exercises in the week leading up to the bombing. The US had the motive, means, and expertise to pull off the bombing. It should be obvious the USA did it.
