I've owned the WTRP below for over 25 years and changed cartridges 3-4 times; never had an issue with adjusting overhang. The arm post does pivot and the cartridge mounting point on my arm version has about a 1/2-inch of travel. The post also moves up/down to adjust VTA and locks with a set screw accessible on the right side of the plinth.
Anti-skate is not adjustable and is provided by the natural twisting action of the monofilament arm suspension as well as the drag of the goop in the cup. Again, it's not something that I've ever found a problem.
Having set up several "traditional" turntables before I owned this one, I wouldn't say it's any more difficult a task. The trick is patience: give the table a bit of time to settle after making an adjustment as the goop provides a resistance that makes it easy to over-adjust. Not unusual to have to tweak azimuth back/forth a bit to get it to settle down where you want it. The knob at the top of the post is used for this.
