ZeroTier is a true "global LAN," basically SD-WAN everywhere, emulates layer 2, and has a rules engine, but does not yet have the IAM integrations that some others have. Guts are very powerful but GUI is more minimal and less mature (as of now).
Tailscale is a Wireguard configurator and P2P hole puncher with IAM integrations and a nice GUI. Runs at layer 3 so it can't do some things that ZeroTier can do, but most stuff runs over IP so only some segments of the market care.
BeyondCorp is more of a concept. Google has their own implementation of it and so do many others.
I too have trouble wrapping my head around this technically speaking. I get the sense that it's basically something that puts your WAN over Cloudflare's network and lets you do access control everywhere in the cloud, which would make it closer to the now-defunct Pertino or some cloud-backhaul-based SD-WAN solutions... but that's probably only a part of it. "One" here seems to refer to "one" bundle of a whole bunch of things.
Hilariously, I can't see whatever is at that link because Cloudflare.
