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.

what is the typical size of Linux updates?
This might be a good use case for RHEL family distribution (such as CentOS Stream or AlmaLinux) or Debian. These are much longer lived distributions, and provide fewer update churn over time than other distributions.

Can't get Nagios to work on Ubuntu 22.04
If If you feel more comfortable on a RHEL based distro, there a good alternatives to CentOS such as AlmaLinux or Rocky Linux.

Rust language forked by community into Crab
This situation still exists and Gregory Kurtzer's RockyLinux (Greg started CentOS originally), CloudLinux's AlmaLinux, and others exist to fill the need for a freely installable RHEL clone.

It's in a bit of an odd location but Alma Linux does provide images with different desktop environments
If you go to https://almalinux.org and click download, then click "Get Live Media Image", you'll be sent to a page with that link as well.

Rocky Linux 8.8 Available Now
Look at AlmaLinux also. I'm not sure of any technical reason why you'd chose one over the other, but AlmaLinux is a public non-profit with a board, Rocky ownership is a private org.

I moved everything to UbuntuLTS also, and I'm not moving again. But if I had waited, and I sort of wish I had, I'd probably be moving to Alma.

what host OS to use for Docker and does it even matter?
I was raised on Debian and I've been using it for all my Linux servers. On my ESXi I use VMware Photon OS as the host OS for my Docker. My primary client is using Alma Linux as the host OS for their Docker deployments.

Rocky strikes back at Red Hat
We have plenty of licensed RHEL, but in isolated environments the hurdle of connecting to a Satellite server or their subscription hub on the internet is too high -- at least with Rocky and the ilk available. For this set up, the licensing model doesn't match reality, at least not easily.
Are we really going to build out compatible configuration management, monitoring, logging, etc? -- it's not a seamless transition. How much time do we have to put towards this?
And yes -- there is software compatibility issues. Look at the OpenHPC software distribution, it's designed for SUSE or Enterprise Linux: https://github.com/openhpc/ohpc/wiki/2.X

job scheduling for scientific computing on k8s?
I recommend you just stick with HPC centric tools are workflows. Your scientists aren’t going to learn k8s as you said. SLURM is the scheduler you want and if you’re new to HPC, I recommend taking a look at https://openhpc.community

HPC usage etiquette.
the general consensus is that pam_slurm_adopt is the better module (that's just one dude's opinion but his citations are good) - the advantage is that not only will it gatekeep SSH access, it'll also drop their SSH session into the cgroups that are constraining the user's resource limits, which also means their CPU usage will show up in sacct for the job (if the user has multiple jobs running on a node their ssh session may get dropped into the wrong one, no help for that)

Looking to optimize research lab resources...
Overall, if you're already in a RedHat-based environment, an installation of OpenHPC is pretty straightforward. Their reference implementation assumes you have a head node for the scheduler that all other nodes NAT through, but that's not a 100% requirement as much as a common setup. It also assumes you can reformat the compute nodes and dedicate them to HPC work, so if you need to keep the systems available as normal workstations, you'll need to deviate a bit. You could also use the OpenHPC instructions as a guide for what packages to install, but it may take longer to get everything right.
