If your goal is to maximize your signal quality and minimize WAF issues, it's hard to beat those in-wall-jack things. Very discrete. Plus, you can just wire up a bunch of outlets as vanilla outlets. Convert later on to APs as necessary.

Note 1: make sure you've got a decent numbering convention for outlets, so you can look at an outlet, scribble down the number, and find the corresponding plug back in your wiring closet, without losing your mind.

Note 2: make sure you punch down and test each and every wire. The sheetrock installers will inevitably damage one or more wires.

Per K447's suggestion, you could also run wires to junction boxes placed discretely up on the wall. This yields APs that are a bit more noticeable, but not any worse than a security system's motion detectors or so many other gadgets that have slowly crept into our lives. Although, for all we know, they aim the antennae upward, so they really want to be installed closer to the floor.
