PS I’m definitely on the hate side today, having discovered that to actually _use_ MS’s implementation of DKIM, I may well have to shell out a 6 figure GBP sum. If anyone can demonstrate to me that outbound DKIM signing in Exchange Online Protection is possible, and working, without any additional Defender for M365 licenses then the beers are on me. So far all my research points to it being a paid-for feature!
I've set up outbound DKIM signing on multiple SMB tenants at an MSP and have heard nothing of needing an extra license. You just go to https://security.microsoft.com/dkimv2, create the DKIM keys, and activate them when you have added the CNAMEs. Since recently, the Admin Panel actually tells you to do this when adding a new domain and selecting Exchange Online. FWIW, all those tenants have used Business licenses, but I have heard/seen nothing to indicate that this would be different for Enterprise licenses.
