Hi @TranquilMarmot, first off, i think the recommendation from @AnonC on their long term approach to registering a domain name is absolutely brilliant! Do that!
Another recommendation you should consider is to find a domain that ends in one of the common top-level domains - like .COM, .NET, or .ORG - because for using with *vital government services* you would not believe how many good natured civil servants (or for that manner even customer service folks in private/commercial companies too!) have no idea that email addresses can end in something other than .com, .net, or .org...and if you try to give them an address that, say, ends in like .FR, or .CC, or .ME, etc...They will try to place a ".com" at the end of it! My experience shows that folks in the U.S. know far less about other TLDs...and are more likely to commit this error, but folks outside of U.S. are perfectly cool with all manner of different TLS. I have had a somesurname.CC domain name as the mailbox for all my family members for more than a decade...and they are all trained to be LOUD and explicit when they communicate to government workers and customer service folks. So, i should have just gotten an easier TLD, but ah well. Live and learn! :-)
EDIT: Forgot to add that choossing the more common .COM, .NET, or .ORG TLDs for a domain name *tends* to be cheaper than many premium domains names. Each registrar wil of course vary, but mostly these tend to be reasonably priced.
Yes, I have definitely run into gov't agencies not accepting non-traditional TLDs before. I still have a .com domain that I use for those vital services.
