There is no such thing as 'best' opening. Each will have their merits and demerits and your choice will depend on your style and your desired outcome for the game. As a beginner virtually anything is playable.
The Sicilian is a sharp opening where black is looking for more than a draw. It is very theoretical and required a great deal of study as better players know many lines 20 or moves long. The theory is always evolving and is often in a dynamic state of flux. You will also have to know many anti Sicilian systems eg the Morra which can be a devil at a lower level, Rosslimov, Wing gambit, Closed, etc.
The Dutch is a sound choice at sub master level. For a beginner is stakes an easy claim over one of the central squares (e4) and many of the moves can be played mechanically whatever white plays
