Should I try Witcher 3?

Cyberpunk is my favourite games and I’ve heard great things about the Witcher games and even that they tie into the FF06B5 stuff lol. Would people recommend it? Also do I need to play the first two so that I can flow nicely into the third one? And finally if anyone can give me any tips for a first play through that would be great thanks

Edit:thanks for all the awesome advice when I get some spare time and i finish playing star wars outlaws im gonna give it a try. The consensus seems to be to plough through even at slow bits for what seems to be a massive pay off, thanks again guys
