I would be interested to learn from other SaaS company on how they run ARR and other metrics in Netsuite

I have in the past created a custom formula field that would convert the Subscription into AAR (total/term*12)

I've done this for a couple of different SaaS companies....but each of them define ARR a little differently.

There's an annual contract value field (on a contract record) if you have SWV provisioned.
