First U.S. nuclear reactor built from scratch in decades enters commercial operation in Georgia::ATLANTA — A new reactor at a nuclear power plant in Georgia has entered commercial operation, becoming the first new American reactor built from scratch in decades.
Statistics would disagree. It is very expensive though, so it should be one of many solutions.

The only issue I foresee with using regular batteries as grid wide storage is cost. Many renewable sources are inherently unstable in output, so one would have to plan for potentially multi day deficits in production.
At least in my country some alternative storage solutions are being planned. One company wants to use excess wind power to produce hydrogen. That hydrogen could then be used to offset potential production deficits.
Otherwise I very much agree with your list.

My personal dream scenario is one, where renewables and nuclear become such cheap production methods, that electricity is cheap and abundant.
At that point one could just use that energy to synthesize fuel to avoid the hassle that is hydrogen storage.
