I have a unique name, think John Doe, and I'm hoping to create a unique and "professional" looking email account like johndoe@gmail.com or john@doe.com. Since my name is common, all reasonable permutations are taken. I was considering purchasing a domain with something unique, then making personal family email accounts for john@mydoe.com jane@mydoe.com etc.

Consider that I'm starting from scratch (I am). Is there a preferred domain registrar, are GoDaddy or NameCheap good enough? Are there prebuilt services I can just point my domain to or do I need to spin up a VPS and install my own services? Are there concerns tying my accounts to a service that might go under or are some "too big to fail"?

I can expand what hangs off the domain later, but for now I just need a way to make my own email addresses and use them with the relative ease of Gmail or others. Thanks in advance!!
