Something like zscaler's ZIA [0] is in the same ballpark as BeyondCorp, or so I think. Cloudflare Warp is basically a CDN turned on its head: Security and privacy are a huge bonus, whilst low latency and high bandwidth remain its salient features. It is more like the Silk Browser [1], the Opera Turbo/Mini [2], or the Chrome FlyWheel [3] but operating at the network layer, and across all apps.
