As far as I'm aware there isn't another facility for exposing metrics related to this in Node Exporter.
This script receives two arguments, the description of the cronjob as a string and the exit status of the previous command. It prints the metric to stdout.
[vagrant@rocky8 ~]$ cat /var/lib/prometheus/node-exporter/cronjob_greeting.prom
# HELP node_cronjob_status Last exit code of cronjob.
# TYPE node_cronjob_status gauge
node_cronjob_status{user="vagrant", description="greeting"} 0

This script was inspired by https://janikvonrotz.ch/2020/09/07/monitor-cron-jobs-with-prometheus-grafana-and-node-exporter/
