To be clear, what I'm after is not just my own account being presented at this step here—but rather a group of accounts that I've curated. That could include myself and a few others that the invitee also knows or that I know they'd be interested in.
“joe” is meaningless in Nostr, since usernames does not exist, it is necessary to identify users by npub/nprofile.
You can personlize Nstart with this syntax:
https://start.njump.me?s=npub1hyxredcavc6ruqgsf4wf4hmakpwnvefmzaspl7dja6a2sxlx0q3sxwtqnx
In the last view your account will be present and pre-selected.

You can add more npubs separated by commas and you will obtain exactly that.
Ah fantastic! Not often you need something and exactly that thing exists.
On that topic (and while I've got your useful brain) some clients like Primal force you to have a Nostr username (the @one, not the display name) that contains no spaces. It won't let you save a profile update if you add a space to the username.
Other clients like Damus allow spaces. And you can quasi-hack Primal by adding a space in to the username in Damus and then coming back to Primal—the one with the space will have been updated in Primal.
Is there any sort of convention evolving there? Space, no space?
The "name" field in a profile can absolutely contains spaces, in fact you can use it for your full name.
I don't know why Primal impose this limit, perhaps it's something related to the fact that they also sell NIP-05 addresses, and these have to be unique, so they are forcing the relation name-address.
