Iranians claim they have mostly deployed older generation ballistic missiles thus far, after they launched a bunch of Shaheeds to overwhelm ashkaNazi missile defence.
Hypersonics (allegedly) have not yet been deployed. I'd assume they're fairly expensive to mass-manufacture. There was footage of very fast impacts, completely running past air-defence missiles like they were balloons. But they may be accelerated, separable warheads
If I were Iran, which has a military doctrine primarily focused on missiles, I'd look at ways to mimic the Oreshnik strike on the cheap. Big MIRV truck with maneuvering warheads that through off missile defence interceptes (David Sling, SM-2, SM-3, etc)
Iran actually has a fairly vast industrial base spread across the entire country. This is seldom well understood in the West, but Iran's partners in BRICs have a much better understanding.
If the political system remains stable and holds out in these couple of weeks, they have the cards in an attritional war. Israel dealt the hardest blow it could by using the element of surprise to their advantage. But even so, initial damage reports suggest they achieved a lot less than what they expected to. They hit a lot of decoys all around. The things they want to hit are usually all underground.
