Key points

Use よ when you are giving information, an opinion or a suggestion that the listener does not seem to know. Depending on tone, it can sound friendly, insistent or like a warning. With ですよ/ますよ it stays polite, but spoken harshly or to a superior it can sound pushy. Unlike ね, which seeks agreement, よ asserts something to the listener, and よね does both.
