I'm a little puzzled by their methodology, it covered noninstitutionalized folks in Indiana over the age of 12, but the majority of deaths in Indiana were in nursing homes. Looks like they were just trying to do the best with the data they could get, but it's not a great estimate.
So far, there is no good evidence that sars-cov2 causes long term lung damage at higher rates than other respiratory infections.
Several of your links are specifically about pulmonary fibrosis. Its a scary condition that has a zillion potential causes, including viral and bacterial infections of many different kinds, pneumonia of all kinds, environmental pollutants, medications, etc. And of course there is the dreaded idiopathic fibrosis -- that for which there is no identifiable cause. It won't be the least bit surprising if scientists discover that most cases of idiopathic pulmonary fibrosis are actually viral in origin.
And again, there is currently no evidence that sars-cov2 causes pulmonary fibrosis any more often than other viral infections. That might change, and the condition is truly scary, but right now the evidence doesn't justify the scary headlines.

People aged 40 or below have a 0.01% chance of dying.
People over the age of 70 have a 1.17% chance of dying.
Overall the chance of dying from the virus is 0.26%.
