Honestly, it mostly comes down to what database you are familar with? and whether or not it meets the needs of your business requirements?
If you are more familar with a NoSQL style of database, then the easy choice would be MongoDB. However, if you are more into relational SQL databases, then MySQL and PostgreSQL are options hard to go wrong with.
If you do go with an SQL database and your project becomes large enough, the then a mirgration to a service such as planetscale.com would be infinitely easier with MySQL.
