Small note, unless it has changed recently, containerd default capabilities list includes CAP_NET_RAW, so hostNetwork=true pods can sniff all traffic.
Edit: reading a bit more about it they will be able to use both Olvid and Tchap, to have a Tchap account you must be a public sector employee so Olvid will be a way to communicate with external contact I guess.
I'm not sure any of the standard Linux tools can show you memory bandwidth usage easily (maybe perf), I know we use Intel PCM (https://github.com/intel/pcm) and AMDuProfPCM (https://www.amd.com/en/developer/uprof.html)
Now there is Attended Sysupgrade https://openwrt.org/docs/guide-user/installation/attended.sy... which makes it really easy to upgrade the whole system, but the user has to launch the process.
Even if you don't buy from them it can give you an idea of what exists, some price ranges and availability. Some outdoor devices (small router + integrated antena + pole mount + weather proof) can be cheaper than a raspberry pi alone, example the TPLink CPE605 cost ~40€ without taxes.
Look for hardware that is supported by OpenWRT, so that all community firmware should work.
