Here is a screenshot of Verizon's Unlock Policy, for both prepaid and postpaid. Unfortunately, it does not mention 5G in particular, but it might be worth a call to their Support team to make sure it's the same.
PEW, your link appears to be the factory unlocked model.
The lower price listed is if you activate in-store on a new line on Verizon: you get a discount on the phone price for doing so.
This should not change the unlocked status of the phone, but you'll be paying for the first month's service on Verizon.
