If a light is touchable from the tub or shower then it must be a sealed, other wise you can put in what you want.

There are CFL, LED, incandescent and halogen lights for both recessed and sconces. Then there are dimmable CFLs, LEDs. Depending on the bathroom size, CFL wall sconces may suffice. Local laws may dictate the use of CFL or LED over incandescent and halogen. For example Title 24 requires that at least 1/2 the wattage is used for approved energy efficient lighting. The main thing is to figure out the aesthetics and then how to achieve compliance with local code requirements while accomplishing the desired look.

Imagine the worst commercial space you've been in, like a 1970s office building with bad fluorescent lighting or the worst fitting room you've ever used. 5000k lighting will be worse. You must see this before you commit to installing it in your home.

Nine seems excessive for a 7X9 space. Yes, two 40 watt equivalent lights is a bit low for vanity lighting. If it was me, I would look at sconces that still sit relatively close to the wall but also take standard bulbs. This may limit choices though. I'd say 6 can style lights would be adequate for the space, but it really is impossible to say without actually seeing the layout of the space and knowing how open the shower is relative to the entire space. I am not a fan of integrated led, although I admit I do use the flat disks that simulate can lights in various places as they can be gotten relatively cheap and install easy on a standard shallow junction box. The shallow j-boxes tend to be quicker and easier to install than cans and are less trouble if its attic space overhead. Overall, I do find it better to get fixtures that you can change a bulb in. Premature LED death is common so when that occurs, its a lot easier to change the bulb than change a fixture. Further, you can work to ensure that you get the color you like for the bulbs. If you get something that is too blue, it's not a big deal to get a different color bulb and fix it. You can also buy a more powerful bulb to throw more light if you find you need it.
