Not everyone will agree with Jesse Jenkins on every point, but he provides some great basic info here in digestible form.

That prototype project converting old oil&gas wells to 2D gravity batteries is a good case study for evaluating tradeoffs in storage. By expectation, longer storage options (seasons, years) might be worth lower efficiencies (e.g., get only, say, 50% of your energy back, but it would be available for years).
Storage eats any overproduction of super-cheap wind and solar, and the cheaper the supply of wind and solar, the cheaper it is to shunt it to long-term storage. I foresee countries’ long term strategic energy reserves to be managed (or co-managed) by governments, just as natgas reserves are now.
