I don't think it's appropriate to hold blame him personally for the police, especially when a number of protesters turned violent (which is all too often the case in France). Cases where peaceful demonstrators were injured obviously need to condemned.
The reason Macron is one of my favorite world leaders is because of his pro-European and socially liberal policies. He has proposed a series of bold reforms to the European Union, making it more democratic, more efficient and better connected as one continent. Unfortunately, Merkel and some others have been lukewarm or outright opposed said reforms. Some of his economic policies like reforming the labor market and raising the retirement age may be unpopular, but are the right direction in the long term. He's taking a similar route than Germany did under Gerhard Schröder in the 2000s, which unquestionably, despite some errors, led to a decline in unemployment and more economic growth.
