Following up on some of the points you bring up, one would certainly expect that opening up will be dependent upon mortality rate, case rate and test positivity oercentage. If I wanted to open up as soon as possible I would advocate for tolerating higher Rates, but would also invest in getting those rates as low as possible, especially in the spring as the vaccine starts to roll out. That would include pushing for freely available low-cost paper test as well as masking.
