With multiple things not being explained to the newer players that do not understand the controls. The camera plays a role in gameplay and to newer players can be confusing. This guide will help you better understand the controls of the camera.

Moving camera- You can use (W A S D) keys. or move your mouse cursor the top, bottom left and right. Doing that would allow you to move the camera more smoothly and to your speed (sometimes).

Adjusting angles of the camera- Using the middle mouse button to zoom in and out give you as a certain angle to look at but you are not stuck as holding the middle mouse button and moving it can move the camera angle to a different side. while zooming in or out holding middle mouse about and moving it to adjust the angle you get that you are comfortable with. But zooming in or out will set it back to default so being able to constantly adjust the angle is not hard and easy and be a habit that you will not notice.

centering on the active unit- shift-f will automatically take you to that active unit.
