I think a lot of that is likely to happen (or at least have a lot of noise made about doing it) on a "so we're ready if something like this hits again" basis. How complete and how effective effective such preparations will turn out to be is another question, of course. As for moving to "work from home" as a standard situation, I remember reading something about why the companies that tried that in the noughties had moved away from it again in the teens - basically, for all the reasons people are discovering anew now, even those employees who don't have any tasks dependent on a physical location as long as they have network access got less done that way. "Here's how we shift to a work-from-home model in emergencies to minimize disruptions" planning yes, but I doubt it'll be a major thing when circumstances don't force it any more than it was before.
