Official install guide is underlining that all the Cloudflare's offerings are still a disjointed bunch. You need to enable billing in 3 separate products in 3 different UIs (while only Images requires an actual paid plan, Access requires a credit card to onboard and Workers Unbound is probably a good idea to enable right away).

Why so much management/onboarding complexity if you really want to compete with AWS as a general-purpose cloud?
