What style of freeze proof water faucet should I use?

I'm wanting to install a new outdoor hose faucet on my house, where there never was one before. The water line feeding it will be 1/2 inch PEX and coming from a heated living space, actually my new laundry room. The line will pass through a 2x4 wall and 1/2 inch OSB, and vinyl siding on the outside.
Do I need a freeze proof faucet or what kind should I buy?
And should I angle the installation of the faucet some how, so water will drain out for winter? ( and how is that done?)
PS: You should know that, Eventually my work, will be inspected by the local code inspector. Thus I want it to pass the first time. One reason I'm asking you experts here.
Attached are pictures of the are where the water line will pass through, and terminate.

Here is a link to some options. These all need to be long enough to pass through the cold wall and be in the heated space. They need a very slight outward slope or level. The water can drain every time after the valve is closed.

Great! thanks Shannon! Now these examples now have me wondering just how long is that pipe? Looking at the images on eBay, it looks to be longer than the 2x4 wall stud will make the wall, thus it would protrude into the interior room. Am I correct?
And that space will be occupied by the clothes washer eventually, and be almost right up against that exterior wall that the water line for the hose faucet passes through! Yikes!!

As I said these need to extend into conditioned space in your homes yes it wld come in past the finished wall. I think the shortest one is 8" long. Your washer usually won't be right against the wall but about 6" away. put a elbow fitting on the end of the hose bib and Pex to that.

Alternatively you could install a standard exterior hose bib (one without the frost proof section) and inside the house in an interior wall not to far away install a valve with a drain. sloth pipe from there to the exterior enough that in winter you shut off the valve inside and open the drain to let in air. Open the outside valve to drain line and leave it open for the winter.
Here is a diagram showing both types.
