My camera offers 4:3, 3:2, 16:9, and 1:1 aspect ratios. Aside from composition preference, are there practical advantages to selecting one over another? Is there any common standard, and should I choose a ratio based on display or print output?

My short answer: Always make images with your full sensor, and crop in post. In your case that's probably 4:3. Why throw away data sooner when you can do so later if necessary?
(Of course, this may be moot if you're shooting in raw and get all the data regardless of the in-camera crop. In that case, shoot with whatever suits your fancy, since you can always change it later.)
Another consideration: If your mental checklist for each frame includes choosing an aspect ratio, that's one more step you need to deal with when making every single image. And I assume changing aspect ratios involves a fair amount of button & menu fiddling.

Usually, the main reason to choose an aspect ratio is the intended final use and composition.
- 3:2 is the classic 35mm/DSLR shape.
- 4:3 is common on many digital cameras.
- 16:9 matches widescreen displays.
- 1:1 is square.
A practical advantage of matching your output is that you may avoid cropping later. For example, a 4x6 print matches 3:2, while a widescreen display suits 16:9. If you know the final print or frame size, shooting close to that ratio can make finishing easier.
That said, a common recommendation is to shoot using the camera’s full sensor area and crop later, especially if your camera records the full image in RAW anyway. This preserves the most image data and gives you more flexibility afterward. If in-camera aspect ratio only affects the preview or JPEG crop, there’s little downside to choosing whatever helps you visualize the composition.
So there’s no single universal standard for all photography—choose based on your output needs, or keep the full frame and crop in post.
