When to send scores for the SAT?

When should I send my SAT scores? I just took my first SAT test and realized that I receive four free score reports until nine days from today. If I take advantage of this, does that mean Score Choice no longer applies, since it’s my first test? Also if, for example, I take the SAT again in June and receive four free score reports again during registration, wouldn’t it be better to send my scores to colleges then (since I get to choose which scores to send for colleges that accept the Score Choice option or all of the scores at once)? When talking about one score report sent to a college, is it just one SAT test score from a specific date or can it be all test scores from any date taken? I don’t see the point of “taking advantage” of the free score reports from the first SAT test if you can send them anyways when you register a second time. I apologize if I’m not clear and thanks in advance!
