That depends on your Mac. The older the Mac, the older the version. On most M1 Macs, you can go back even to Big Sur, on M2 it's usually Monterey and so on. It might be different with the Pro/Max/Ultra variants though.

In Hungarian it says "segglyuk", but that means "asshole". It should be "segg" to match "ass".
Well, the routes might manifest somewhere as files, but I don't expect anyone to be able to viably parse them without commands like ip
or ifconfig
(or know where the files even are).
Some devices (like disks for example) are very straightforward to use as files, while some other special files (like USB devices) are so weird/ugly to use that everyone uses tools/libraries to access them (like libusb).
This is very off-topic, but there's a great talk by Benno Rice that talks about this (among many others): https://youtu.be/9-IWMbJXoLM
They aren't asking about changes to a file describing the routing config, rather the actual in-use routing config. Unless the routing rules are modified through a couple of files (which I doubt), this doesn't answer the question.
Cool commands though.
I don't know anything about how Firefox is packaged for snap, but snap's "sandboxing" might interfere with getting all fonts.
You might want to try using Firefox without snap (which has some other benefits, especially around startup time) or adding ~/.local/share/fonts (which is where fonts are supposed to be installed for users) to some sort of allowlist.
Also, USB4 can optionally support PCIe tunneling, which is a fancy way of saying it supports plugging more advanced types of hardware in (like GPUs, high-speed network cards or NVMe SSDs) at speeds of up to 40Gbps.
And there is USB4 v2 (not kidding, that's the name) which extends USB4 to up to 80Gbps, but there are no devices that support that yet.
