Keeping self-hosted Bitwarden up to date automatically

I have a self-hosted instance of Bitwarden running on a Debian10 server. What is the best option to keep this up to date? I have seen recommendations of using crontab or watchtower. If I use the crontab should I use the Bitwarden user crontab with the following entry to run weekly?

0 2 * * 0 /opt/bitwarden/bwdata/scripts/ >/dev/null 2>&1

/opt/bitwarden/ updateself
/opt/bitwarden/ update

I will also be snapshotting the VM and running bwdata/ backups weekly just before the updates run.
