I have the opposite problem: Living in Texas, my garage easily gets above 110F many days during the summer (it would be crazy to pay for A/C in it). But, I'm also not going to put the battery pack(s) "inside" my house (e.g. utility/laundry room).

Why not? The whole point to making it wall-mounted is that it won't take up any substantial amount of space. A utility/laundry room seems like exactly the logical place that you would want to put it.
My electrical panel is in the garage. Knowing my existing plans to add solar panels, a generator and transfer switch that's the only place battery pack(s) could go. Except it will be above the max temperature for a good period of time, and even below the minimum other times.
Sure, there could be some trade off where it makes sense to add heat and A/C to my garage (and appropriate insulation) based on the economics. But, that's even more I need to spend.
The big technological thing Tesla batteries have going for them is, short of complete mechanical destruction, they don't catch fire. There's a thermal shutoff on every cell. So not the big issue it might have been.
It may not make much of a difference from the overall perspective of damage, but it certainly makes a difference in warning and escape time. Also, the chance of dangerous fumes while trying to escape is lower.
Depends on design. Garage could share a wall with a bedroom and the laundry could be on other side of the house or vice versa. I would say that garage may be the most obvious choice, but not always.
