One of the most important aspects of a camera is the size of its sensor. A larger sensor will capture more light, which results in improved low-light performance, dynamic range, and general image quality.
The more focus points the more flexibility in picking which part of the scene to focus on. They also give the image sensor a better probability in identifying the right area of the scene to focus on in more automatic modes.
The number of megapixels determines the resolution of the images captured with the main camera. A higher megapixel count means that the camera is capable of capturing more details. However, the megapixel count is not the only important element determining the quality of an image.
With a higher light sensitivity (ISO level), the sensor absorbs more light. This can be used to capture moving objects using a fast shutter speed, or to take images in low light without using a flash.
Expanded ISO allows you to go beyond the native ISO. It does this by digitally enhancing the image output. The resulting image will have less quality than when staying within the native ISO range, but it can be useful in certain situations.
With sensor shift, the image sensor (rather than the lens) moves to counterbalance any vibration of the camera. This means the image will be stabilised regardless of what lens is being used.
Fast continuous shooting is useful for catching action shots.
With AF tracking, once you choose the subject and press the shutter release part way down, as the subject moves, the autofocus will follow it. No more out of focus shots.

Sony has always been good at designing their camera casings to the extent that the tech specs are a real treat for their customers' eyes. Unfortunately, the reality of actual use always catches up with unrealistic technical promises. The A7 III falls short in many areas such as: ergonomics, compactness, complex menus, the lack of a swivel screen, its features - it doesn't have full HDMI, it's not ventilated, no tools such as waveform for exposure, etc. The most problematic point is the image quality in low-light - as ISO ramps up, the image gets oversmoothed too quickly and there are large color shifts, the color science is very video game-like.
