Don't know what price you're comfortable with, but Protectly has a lot of options at different price points:
I've found these to be the most comfortable to wear (and they're designed to prevent glasses fogging, if that's something that matters to you):

Amazon shouldn't allow anyone but 3M Authorized distributors to sell 3M respiratory protection
For FBA (fulfilled by Amazon) listings, that is indeed the case for listings with the correct brand.
Questionable sellers get around it by using another brand, for example
https://www.amazon.com/dp/B09HY48BK6
Note the * after 3M in the brand. Clicking on it will take you to a page that shows one other listing with this not-actually-3M brand name, for an 1860 -- another heavily counterfeited 3M surgical respirator.
Here's another: https://www.amazon.com//dp/B09GTKFQD9
"3M" is in the item title, but the brand is "Med Lab Supply"
Legitimate 3M retail branded products will show "Visit the 3M store" as the brand name -- for example https://www.amazon.com/dp/B095FJ36H2
3M products intended for "professional use only" will simply show "3M" as the brand, for example https://www.amazon.com/dp/B08J1THV9G, with that link taking you to https://www.amazon.com/s?k=3M, which is also redirected to from the short url https://www.amazon.com/3M
From that short URL, you can (on the left sidebar) select the "Respirators" department then "Amazon.com" as the seller. Direct link, sorted by ascending price.
Amazon carries much of 3M's commercial respiratory protection line, or lists inventory from their partners who fulfill on their behalf -- primarily Magid Glove, Global Industrial, and AGO Now.
It's all about fit and personal preferences, but...
In terms of N95 respirators, some of the better current ships from / sold by Amazon.com options are:
3M 9105 | 3M 9211+ | 3M 9205 | 3M 9502+ | 3M 8210 | 3M 8511 | Moldex 4200N95 | Dräger 1750
EDIT: fixed Dräger link -- I added marketplace codes for ships from / sold by Amazon, but Dräger sells directly through Amazon like Halyard and BNX (Accumed), rather than Amazon being a distribution partner like their arrangement with 3M... So I needed to use Dräger's marketplace ID on the link.
Wear an N95 respirator the entire time? These ones are fairly comfortable: 3M Aura Particulate Respirator... https://www.amazon.com/dp/B095FJ36H2?ref=ppx_pop_mob_ap_share
