Front Door

Redirects in Azure using Front Door

I suggest we create a new Azure Front Door profile specifically for this purpose and have Azure provide and manage certs for it: https://learn.microsoft.com/en-us/azure/frontdoor/front-door-custom-domain-https#option-1-default-use-a-certificate-managed-by-front-door

We can implement the redirects as rules in Front Door.

We would also need and want to switch our authoritative nameservers for those mistyped domain names to Azure Public DNS in order to support them as apex domains: https://learn.microsoft.com/en-us/azure/frontdoor/apex-domain

I wouldn't use the existing Front Door. I would suggest building an additional one so we don't consume Front Door's per-profile quotas on the existing one.
