It's a fire. It can kill you. Nothing the internet says will make it safe. There is no trick. There are no hacks. None of your stuff is worth dying for.
Good luck.
OP says they have time. It would make sense to do proper packing and the simple photos and videos of the house.
I doubt anyone is saying to do this stuff if you're in serious imminent danger. And overall following what local authorities are saying is a good thing to do too. Perhaps there's a reason OP shouldn't leave right now. We don't know what's happening there.
The median time of "the next 24 hours" is twelve hours away. The first quartile is six or fewer hours away. The worst case is not a homeowner's insurance headache. It's dying. All of those are premises of the statement "Your house might burn down in the next 24 hours."
If a doctor told the OP, "If you don't do X, there is a good chance you will die in the next 24 hours," what priority should the OP place on X versus photographing their household's personal property?
"in the next 24 hours"
You forgot to read the title.
