Blue, welcome to the forum!
Besides the floor, you might have damage to the lower part of the walls. These can all be repaired of course, but you'd need to decide on that for yourself.
Unfortunately, if there was 9" of water inside, the lift pump and motor were also underwater. Electrical components don't like to be submerged, so the motor may well be damaged to the point that it would need to be replaced. Check that the top lowers and raises too. The motor is used to raise the top, it lowers by just releasing hydraulic fluid back to the reservoir.
You could also have some damage to the furnace, the hot water heater and especially the refrigerator if the water was high enough. Do a thorough check of these items.
