Fortunately you don't need to vary the .install file, you can use
dh_installinit and dh_installsystemd to insert their own snippets into
postinst etc. and they will make the right decision at install time.

Even more fortunate is that you are the Debian maintainer so there will be no problem on that front!

Here's an example of adding an initscript to a package with systemd integration:

<https://salsa.debian.org/dns-team/getdns/-/commit/2bba775416ffa72cf48aca45c90ea22121b6ee31>

I think you can probably get rid of the stuff you put in for systemd in postinst, as well - dh_installsystemd lets you decide whether to stop on upgrade etc.

When you install cron jobs make sure you detect if systemd is present, like this:

<https://salsa.debian.org/pkg-security-team/acct/-/blob/debian/master/debian/acct.cron.monthly?ref_type=heads>

I can help you out more if you like!

BTW I think you need to merge into salsa the changes your sponsor made before upload.
