The Pipeline snippet syntax generator will show you all the options available with the Pipeline version you have installed and the plugins you have installed.
I created a 90 second video for the git plugin that may help.
However, the specific options that you show in the screenshot are configuration options for a multibranch Pipeline. Those options control the actions taken by the Jenkins controller when it is checking Bitbucket for changes in the repositories. There isn’t a declarative Pipeline at that point, just branch discovery. There isn’t a way to express those options in declarative Pipeline.
