templates: spring-mvc offers first class support for Thymeleaf, Freemarker, Mustache and Groovy Templates. Is having 4 equal choices too much for you? Spring seems to endorse Thymeleaf.

persistance: spring-data, the JPA/Hibernate based library for SQL access appears to be very opinionated and is very simple to fully understand. I have never used MongoDB, but spring-data-mongodb is probably of equal quality.

DB migrations: What do you mean?
