Contract first and code first approaches
Both contract first and code first development modes are fully supported by CXF Extensions for Quarkus.
A SOAP service is described by WSDL.
It is a contract defining operations, their parameters and return values, etc.
WSDL is rich enough to be used for generating the code of a complete client.
CXF provides the
wsdl2java utility for that.
CXF Extensions for Quarkus wraps
wsdl2java in the
quarkus-cxf extension so you do not need to use it directly.
Please follow the Generate the Model classes from WSDL section of the user guide for more details about how to use it.

When implementing a service the generation of Java code from WSDL
may also come in handy.
wsdl2java can generate the model classes (with JAXB annotations)
and service interfaces (with JAX-WS annotations) for you.
Your task is then to provide implementations for those interfaces.
You may want to check the WSDL First Service Development section of CXF documentation for a better understanding of the underlying concepts.
Another valid option at your disposal is to write your service in Java, using JAX-WS and JAXB. Then you have two options how to obtain the WSDL contract:
