thanks patrice-n! this code worked to get both queued and running jobs and their parameters:

import hudson.model.Job
import hudson.model.ParametersAction
import hudson.model.Queue
import jenkins.model.Jenkins

println("================================================")
for (Job job : Jenkins.instanceOrNull.getAllItems(Job.class)) {
    if (job.isInQueue()) {
        println("------------------------------------------------")
        println("InQueue " + job.name)

        Queue.Item queue = job.getQueueItem()
        if (queue != null) {
            println(queue.params)
        }
    }
    if (job.isBuilding()) {
        println("------------------------------------------------")
        println("Building " + job.name)

        def build = job.getBuilds().getLastBuild()
        def parameters = build?.getAllActions().find{ it instanceof ParametersAction }?.parameters
        parameters.each {
            def dump = it.dump()
            println "parameter ${it.name}: ${dump}"
        }
    }
}
println("================================================")
