Assuming the exterior sheathing to be fastened to the wall framing is being used to complete a Wood Structural Panel (WSP) its function is to provide resistance to the horizontal shear force wind pressure and earthquakes can exert on the structure. So, if you choose to deviate from the current code (2018 IRC, September 2020 edition, Table R602.3(3)) in an attempt to exceed (or improve upon it) you have to bear in mind the implications of choosing to use fasteners that are different in either length or diameter from the IRC and, most importantly, conform to what your local building inspection office would accept. The current IRC specifies the necessary fasteners for exterior wall sheathing applied to a WSP based on the thickness of the sheathing.
As an example, the sheathing you've opted to use is 19/32" plywood. Table R602.3(3) would define the MINIMUM fastener requirement for sheathing exceeding 7/16" in thickness as an 8d nail 2-1/2" in length and 0.131" in diameter AND a minimum penetration of the framing of 1-3/4". Okay, that's a lot of numbers to keep in mind when selecting the nail you plan to use on your sheathing. But keep in mind that these characteristics define the "minimum" fastener you can use.
Based on the current code using 19/32" plywood you'd need a nail at least 19/32" + 1-24/32" = 2-9/16" in length to achieve the required minimum penetration of the framing when fastening the sheathing to it. Where I live the nail commonly used with pneumatic nail guns to fasten wall sheathing of any thickness is 2-3/8" long, 0.113" diameter, in part, because this nail is so readily available. You'll note that this 2-3/8" nail is both too short (by 3/16") and just a bit too small in diameter (by 0.018") to meet the minimum code requirement for fastening 19/32" plywood.
What to do? First, keep in mind the code prescribes the MINIMUM fastener. You can choose a nail that exceeds the minimums of all three of the parameters of this prescription. What many framers do is to simply increase the number of nails they use to fasten the sheathing to the framing. This means decreasing the minimum nail spacing from the code specified 6" along the edges and 12" in the field of the sheathing to something like 3" along the edges and 6" in the field. But use caution in assuming simply adding more nails compensates for your deviating from (or improving on) the code minimum. I've come onto jobs where the framers used so many nails spaced only about an inch apart om 7/16" thick sheathing that the strength of the sheathing itself had been compromised; effectively diminishing the effectiveness of the function the WSP was designed to perform.
There's not much worse than tearing out new work and redoing it to make it code compliant whether it is yours or someone else's you were brought in to fix.
When in doubt bear in mind that the code specifies the minimum requirement and your local building official - not the store salesperson who tells you "that's what everyone else uses" - is the best resource to do it right the first time.
Such an approach can be workable BUT you should check first with your local building inspector to make sure the fastener you select meets their interpretation of the current code.
