When my rental house flooded, we went with a fire & water restoration company, followed by a residential contractor. The restoration company did all the demo, moisture tested the remaining walls, advised what surfaces needed replacing, and brought in commercial-level dehumidifiers. These were the size of a recliner. I would have been lost on what to remove, and may have removed too little without them. The restoration company worked directly for my insurance company, and helped us to establish what they would pay for (essentially everything removed they would pay to replace).
The residential contractor happened to be a brother-in-law's company. They used kitchen cabinets from Home Depot - they come assembled already. And a custom countertop - we used formica since that's similar to what was in the house before. We replaced the old hard wood floor with LVT, and moved a wall dividing the kitchen from the hallway. You now have to walk through the kitchen to get to rooms, but getting rid of the hallway meant doubling the size of the too-small kitchen.
The renovation ended up so good, and the pain in the butt from the damage so stressful, that we decided to sell the place.
