Choose by MDM and by what the relying party needs. On Intune, SCEP is the documented Wi-Fi path and the choice is which CA sits behind it. On Jamf Pro, use the ACME payload with Attest where the relying party needs CA-verified attestation, the fleet is Apple silicon on macOS 14 or later or A11 and later on iOS, and the CA supports device-attest-01; use the ACME payload without Attest where an optionally hardware-bound key from an ACME CA is enough; keep SCEP where the CA is AD CS or the built-in CA, or attestation is not required. In every ACME case on Jamf, turn on automatic redistribution and check the template accepts the OU Jamf inserts.
