Since day trades that lasts for seconds and  takes advantage of the short-term fluctuations of an asset's price, I think what suits you best is day trade since you are a beginner, because the positions are opened and closed within the same day so as a beginner you will be anle to see what you worked for on that same day. While long trade needs to be managed for months and years so if  a beginner will do it I don't think you'will find the will to finish or continue it.
