More megapixels are really useful for commercial uses, such as large portraits, or landscape photos. They also allow even the average photographer to crop a little more heavily and still have an image with good resolution.
There are definitely some downsides. As you indicated, the file sizes are large and you need to be more discriminating about what you keep on your hard drive. Aside from that, if you intend to crop heavily, you will want to have good glass in front of that high MP sensor. The 36 MP D800/810 cameras give you enough resolution to find flaws in every lens you own. Lastly, denser sensors don't do as well in low-light / high ISO shooting. I have noticed that my 16 MP D4 kicks the butt of my newer 24 MP D750. When I expressed that opinion to a Nikon rep a couple of weeks ago, his response was: "There's a reason why the current Nikon Pro Camera (D4S) is still a 16 MP camera." The higher the pixel density, the greater the problems with noise at high ISO.
