I think the benefit of using Bolt12 is that you can print out reusable invoices (QR) set to a certain amount
So, it's a POS thing

You can do that with lightning addresses too 
Is this static or do you have to generate a new one every time?

That’s only payable once. Mine is static and is reusable.
And you can create LNURLs with fixed amounts. Just set the min and the max amount to the same value. Easy to do with LNbits.
Is this reusable

Nope
How do you make a reusable one?
You can just make a QR code from your lightning address
