The phrase "cautious estimates" is correct and can be used in written English.
It is typically used in situations where someone is making an estimate or prediction but wants to show that they are being careful and not overconfident in their prediction. Here is an example: "Based on the data we have, our cautious estimates suggest that the company's profits will increase by at least 10% next quarter." In this sentence, the speaker is making an estimate about the company's profits but using the word "cautious" to convey that they are not certain and want to avoid being overly confident in their prediction.
