Issue
I would like to have a Jenkins Pipeline that will conditionally run specific stages depending if a file exists on the filesystem.

Resolution
Generally this use case may not a best practise, as relying on files on a filesystem can sometimes mean you have files that are outside of source control, but there are some situations where this is valid.
pipeline{
agent any
environment{
MY_FILE = fileExists '/tmp/myfile'
}
stages{
stage('conditional if exists'){
when { expression { MY_FILE == 'true' } }
steps {
echo "file exists"
}
}
stage('conditional if not exists'){
when { expression { MY_FILE == 'false' } }
steps {
echo "file does not exist"
}
}
}
}
