I’m not familiar with Jackson 3 and how it manages time API, but is Joda still a thing?
From where did you take this dependencies arrangement ?
Why there are no more for time, for example and parameters?

In Jackson 3, "parameter names" and "datatypes" modules are now built-in.
JSTEP documentation: https://github.com/FasterXML/jackson-future-ideas/wiki/Jackson3-Changes#maven-modules-jars-java-packages

For Joda, I added it by referencing our Jackson2JsonObjectMapper. I tested it as shown below, and without adding JodaModule, Joda couldn't be supported.

public static class JodaData {
    public String name;
    public org.joda.time.DateTime createdAt;

    public JodaData(String name, DateTime createdAt) {
       this.name = name;
       this.createdAt = createdAt;
    }
}

@Test
@DisplayName("[Jackson3] With JodaModule")
public void testJackson3JodaSerializationWithJodaModule() throws Exception {
    tools.jackson.databind.ObjectMapper mapper = JsonMapper.builder()
          .addModule(new JodaModule())
          .build();

    DateTime jodaDateTime = new DateTime();
    JodaData data = new JodaData("John", jodaDateTime);

    String json = mapper.writeValueAsString(data);
    mapper.readValue(json, JodaData.class);
    System.out.println("✅ Joda works with JodaModule in Jackson 3");
}

@Test
@DisplayName("[Jackson3] Without JodaModule")
public void testJackson3JodaSerializationWithoutJodaModule() throws Exception {
    tools.jackson.databind.ObjectMapper mapper = JsonMapper.builder()
          .build();

    DateTime jodaDateTime = new DateTime();
    JodaData data = new JodaData("John", jodaDateTime);

    Assert.assertThrows(tools.jackson.core.JacksonException.class, () -> mapper.writeValueAsString(data));
    System.out.println("❌ Joda doesn't work without JodaModule");
}

There are many changes in default configurations and other aspects. To save our time, I'll leave review comments with references to these changes in upcoming PRs!
