Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Helm is both "package manager" and "templating engine" - probably the best package manager but horrible template engine
We use kapp-controller when applying our charts (it uses helm template instead of helm install) so we can be very rigorous about what fields are changeable (like through pod autoscaling) and what are not (securitycontext, etc.)

How to handle the lifecycle of multiple COTS
Even further, you could describe your "fetch", "template", and "deploy" stages in akapp-controller AppCR and then you'd have a controller (like an operator) running the cluster continuously reconciling your private cloud to ensure that it's always reconverging to the desired state. This is basically what's underpinning a number of VMWare's commercial (and OSS) Tanzu offerings, as well as some other organization's internal platforms, or "self hosted private clouds"

ArgoCD vs. crossplane-helm provider for managing helm releases?
Full disclosure: I work on https://carvel.dev/kapp-controller/ which can also continuously reconcile helm charts (via our own CRD ).

Ask HN: How would you set up a new B2B SaaS?
We have helped clients several industries and sectors where these words either mean different things, or people who use them are thinking of different things. An appliance has meant a physical thing before it has also meant a VM.
The question you have asked includes a solution. Many client meetings start with that. This is what's called an XY problem[0], where the client says they want want Y, but that's their implementation of a solution to solve X. That may or may not be the only solution, but finding out the actual problem to be solved has never hurt me and saved a lot of time and money.
This is why we spend time defining the problem and stripping away every ounce of jargon we can, because that jargon can create a bias towards a solution that may not be optimal. For example, site-to-site VPN. Why? Gateway ? Why ? These are solutions. What's the job to be done.
Anyway... Have a look at https://www.replicated.com/ and https://kots.io/
