Whilst you have a good point for the present, it is noteworthy that medical professionals working in covid wards (and so the ones with FFP2/equivalent or better) had, in the studies I have read, consistently lower rates of infection than even other hospital workers (with only surgical masks) during the first wave.
I recall seeing studies from the UK and US showing this, and possibly other countries.
