I am always suspicious of "special circumstances" for any online or non in person sales.
The buyer may well be legit but do a bit of checking and use common sense every step along the way.
The "temporary" address screams chargeback to me.
PayPal payment safeguards are largely subject to the payment source. If it is a credit card payment, there is typically a 90-day window for chargebacks or disputes. If it is a hacked account the owner may not notice for some time. I ignore my PayPal account and leave small balances in there for months at a time.
Google and google street-view the address before shipping.
Where is the temporary address? Can you find a gallery or dealer that would be willing to more safely do an in-person sale for you?
If it is a freight forwarder or mailbox company? A company I was working for that sold performance car parts got scammed. The buyers used stolen domestic cards and shipped to a domestic address that happened to be an international freight forwarder in Florida. Our parts guys shipped several orders there before we started getting chargebacks. We reported it to the police and FBI. Never saw any follow-up. We changed our CC policy to only ship to verified addresses linked to the payment account after that.
As far as asking for a check instead, that seems more problematic to me. A bad check, particularly a bad foreign check, can take weeks before it backfires on the seller, you lose your money and the merchandise is long gone.
Wire transfers - Some years ago I was liquidating some surplus networking equipment, I had a sale for ~$20k and the buyer wanted to pay via wire transfer. I talked to my bank and expressed my concerns. They had a holding account that they used for such circumstances and we used that account instead of exposing our business account number to the buyer.
Having said all that, I'm not sure what the goal of the scam here is, if it is a scam. Unless it turns into a cash-back scam, in which case, you have your answer.
Scammers typically are not interested in the merchandise in a transaction, only getting cash out of the deal. The exception would be electronics or maybe car parts, which are easy to flip. A piece of art such as on of your bowls is likely not easy to turn for quick cash.
