Exploring cgroups v2 and MemoryQoS With EKS and Bottlerocket
Back inside the sheltie prompt let's explore the containers running on Bottlerocket. Bottlerocket OS is using containerd container runtime. In order to interact with it we'll need to use ctr.

Access for Infrastructure: SSH
There's not one answer to your question, but here's mine: kubelet and AWS SSM (which, to the best of my knowledge will work on non-AWS infra it just needs to be provided creds). Bottlerocket <https://github.com/bottlerocket-os/bottlerocket#setup> comes batteries included with both of those things, and is cheaply provisioned with (ahem) TOML user-data <https://github.com/bottlerocket-os/bottlerocket#description-...>
In that specific case, one can also have "systemd for normal people" via its support for static Pod definitions, so one can run containerized toys on boot even without being a formal member of a kubernetes cluster

Flatcar: OS Innovation with Systemd-Sysext
Don't overlook Bottlerocket, which despite coming out of AWS is not (AFAIK) AWS-centric: https://github.com/bottlerocket-os/bottlerocket#readme
It's also super handy for writing out static Pod manifests to have replace the brain-damaging Ignition as a less stupid alternative to cloud-init

Exploring cgroups v2 and MemoryQoS With EKS and Bottlerocket
According to this discussion - starting with Bottlerocket 1.13.0 (Mar 2023) new distributions will default to using Cgroups v2 interface for process organization and enforcing resource limits.

Bottlerocket – Minimal, immutable Linux OS with verified boot
Well, the link I provided references the Bottlerocket docs which explains the control container and the admin container and also how you can configure Bottlerocket via the User Data field when launching it as an AMI. All the information appears to be in the docs

Introduction to Immutable Linux Systems
On the server-side, there's Bottlerocket OS [1] (Amazon). They use A/B partitions for upgrades, and the idea is that you just run containers for anything non-base. Boot containers are used to do custom configuration at boot, and host-container (or DaemonSet, if you run K8S) is used for long-running services.

Wolfi: A community Linux OS designed for the container and cloud-native era
To add to the other excellent answers, I would recommend adding Bottlerocket to your reading list: https://github.com/bottlerocket-os/bottlerocket#readme
I'm also aware of (but haven't used) https://github.com/siderolabs/talos#readme
I just realized your question may have implied a desktop os, whereas Bottlerocket, Flatcar, and likely the others in this specific thread are server-side. I don't have much experience with trying to solve that problem on the desktop except for the horror-show that is snap
