I’m sorry that this is all I have to contribute, I don’t know anything about the duration of contagiousness but I still have some potentially decision-relevant factors.
You want to use p100 masks, not n95 masks (they are available at large hardware stores and Amazon). My model since last winter is that the current strain infects most people who aren’t wearing p100 masks when they go to shared indoor spaces, although the herd immunity since then might mean that it’s infecting closer to 10-50% of the country (US) instead of 95-99%.

The rapid antigen tests have a history of really high false negativity rates: https://www.lesswrong.com/posts/T4H7w6BqB6mnm9JYq/how-much-bayesian-evidence-from-rapid-antigen-and-pcr-tests but this doesn’t mean they are sensitive in a trustworthy way, it’s more of an indicator that the people making them aren’t trustworthy people.
