p-channel MOSFET switch
First off, the rules of the site do state not to ask for recommendations of products, so I will skip that bit. Just read the datasheets as everything will be explained in there. If there is something on a datasheet you do not understand, please post a separate question about it.

Now, on to your problem. From what I think you are trying to do, you may find you might not be able to toggle the PMOSFET fully, or you may have some difficulty unless you understand the datasheets properly. What may be an easier idea, is to use a MOSFET pair, where you toggle an N-channel MOSFET to pull the gate of the P-channel to 0V, like so:

I have used this circuit a few times with no issues. However, as always, make sure to read the datasheets to make sure your components are able to do what you want. You don't always have to use the same components as shown in example circuits. Base your components on your own needs. Example circuits are great for learning how things work, but are not always the most practical. When it comes to designing your own circuit based off an example, you should always consider your own needs, and base your component choice off of that, rather than just use whatever the example has.
