I use Qubes OS for stuff like this. Way better security, no need to juggle tokens, dedicated lans and so on. Only real problem is no graphical acceleration in browser (Google Earth...)
I would love to use it, but most of the use cases I would like to try it for are much more in the realm of SBCs with 2-8GB of RAM for running services locally. It would be great to have that extra security, but the cost is really really high.
32 GB minimum, but 16 GB recommended.[0] I think that's backwards, so I'd say it's actually 16, not 32 required. But yes, that's more than a typical SBC will have. The Pi 4, for example, has a maximum configuration of 8 GB, but some have modded it to have 16 GB.[1]
