I like to "shoot to a known white balance" on many occasions. The Nikons I prefer have a very simple, dedicated WB button on the lower back area; press the button, and then spin the front command wheel, and white balance can be cycled through the various pre-sets, as well as dialed effortlessly in to different Kelvin temps.
Metering modes are used, as appropriate. For panning (and helicopters!), I often use Shutter speed priority, because panning subjects are usually moving, and the EXACT speed is the most-critical variable when panning. F/stop is usually not hardly relevant at all, but if you want a helicopter's rotors blurred, you need to have the speed be "slowish". If you want bicyclists blurred, the range is from 1/3 second to about 1/60 second, depending, so Shutter speed priority auto, what Canon calls Tv, is my usual choice if the subjects are going to be coming up offhandedly, unpredictably, or moving through a wide range of lighting conditions. Same with horse racing at the State Fair's track, where the horses come from brilliant, full sun, into deep shade for the last 100 yards, where the grandstand shadow cuts the light about five f/stops, and you have like 1.2 seconds to change from full sun to deep shade exposure...AUTO exposure is the easiest way to go.
I use Aperture priority auto quite a bit. I'm used to it. It works well, and I can see the speed the meter suggests in the finder and on top. If I know it'll be wonky, I dip the metering circle up or down, to a brighter or darker area to bias it, then hold the AE-L button to hold the meter where I think it needs to be. Nikon has a scribed, 12mm diameter circle on the viewfinder screens, and that's 60% of the meter weight, 40% on the remainder in default mode; the degree of metering emphasis given to the center circle is user-adjustable on my cameras.
But to answer the question of metering mode; I seldom need to change that very often. If I am shooting FLASH, 99.9% of the time I am in manual mode. Flash shot in P,S,or A modes is to me, just a PITA...it yo-yos like a SOB...I can't stand shooting flash in any mode but manual, and that .1% out of the 99.9% I am just putting in there as fudge factor when I need to shoot beer bottles swirling around in floodwaters at dark, during a monsoon in Thailand...
Hirejn has some good tips; I too use exposure delay on slow-speed, tripod work. I never use that stupid beep sound. Set as many parameters as **you** need, for your own shooting. For example, if you shoot Aperture priority auto with a fully color-aware, distance aware Nikon, then set the metering pattern to MATRIX. If you shoot Manual exposure mode, then set the camera to CENTER-weighted metering, or Spot. The three metering patterns are not created equal.
