Also, "2020-05-26: MongoDB identified a bug in the transaction retry mechanism [2] which they believe was responsible for the anomalies observed in this report; a patch is scheduled for 4.2.8." [1]

Those same issues exist in most NoSQL databases. If you're going to avoid MongoDB for data safety reasons, you should just go straight to SQL.
