On your second point, the Mayor Clinic states explicitly that masks protect the wearer from getting infected by other people. The NIH says the same, as does the CDC. Besides that, N95 masks were quite difficult to get during the pandemic. I never saw them for sale. The closest I found was KN95, which are made to a more lax standard and difficult for me to breathe through.
Fair enough they seem to give some protection to wearer if you wear it properly, but still way less protection than an N95 respirator. As you said the main reason people wear masks over N95 is because of price and availability.
