Feedback requested - customer engagement strategies

I have been tasked with creating a customer engagement roadmap for our team summit that is taking place week after next.   For reference:

• Team is very new with little process in place (all being built)
• I am very new to customer success

That being said, I've started with identifying some strategies that I think would work for our customers (see attached).  I would really like some feedback from the experts in the field.

A little about our company/product, we are a SaaS company that does evacuation zones and planning for public safety.  My expertise before joining this team is emergency management.  One of our OKRs is increased monthly users.  Where I struggle is, putting my EM hat on, once the zones are in place and all the planning elements have been done, I wouldn't have a need to login back in unless it's time for the annual review/training or an incident happened.  So in cases of products like that, ones not typically used for day-to-day work, how do you keep customers engaged?

Thank you,
Tammi
