Is there a difference in effectiveness depending on the type of filler?

I am considering filler treatments and am curious about their effectiveness and the differences between the various types. I want to know if they are primarily used to fill in sunken areas or if they also help improve wrinkles or enhance facial contours. I am also curious about how the duration of effect and the feel differ depending on the type of filler, such as hyaluronic acid or collagen. I would like to know if there are specific fillers suited for different areas—for example, which types are more commonly used for the forehead, nose, lips, and nasolabial folds. Additionally, I am wondering if the results are noticeable immediately after the procedure, and how long the recovery period is, including issues like swelling and bruising. I have so many skin concerns these days, so I look forward to your answers.
