I'd say the risk is exaggerated. Unless it arrives at the post office damaged/leaking theres going to be little to no reason to inspect further. It has to process through the post office anyways. I've done both and with a large PO Box every package I received fits, no need to interact with anyone, and all hours pickup. If they suspect you are shipping illegal goods they will investigate whether it gets delivered to PO Box or home. Of course it doesn't improve opsec and security footage sucks.
According to USPS website, 4,754 arrests were made by inspectors in 2024. Who knows how many additional cases were referred to other law enforcement but having a PO box vs using a home address seems like it doesn't increase your risk much.
