CB Auto Welcome acts on onUserActive, which is triggered when their account becomes completely active. So it should work fine regardless of how they login as long as their account is completely active (confirmed and approved). If they are completely active and it doesn't work ensure CB Auto Welcome is published and public in CB > Plugin Management and ensure under Parameters the user id parameters (e.g. Key User Ids) have an actual users id (if using multiple then separate with a comma with no spaces).

Note connections need to be enabled in CB > Configuration > Connections for it to establish a connection. For PMs you need to be sure Private Message System plugin is published as well.

I’m assuming my issue may be in the user Id.. my admin id is not the “62” that’s default.. it’s “283”. But even with that id it’s not sending from there.

For PMS be sure you set "PMS Sender Id" to 283 and for connections set "Key User Ids" to 283. Then for PMS ensure "Automatic Welcome Message" is set to "Yes" and "Notification Method" is set to "PMS Only". Connections also need to be enabled by setting "Automatic Connection to key user" to "Yes". It should be working fine if all those parameters have been set correctly. Are you using UddeIM or the Internal usage for PMS?

Have retested CB Auto Welcome and is working perfectly fine in my tests. Are you using normal CB registration to register users? If you're registering them by any means other than through CB that plugin will not work. As for if the user id you supplied is correct it's the number under the far right Id column in CB > User Management. Try using a different user id other than 283 then test registering a user to see if they receive the PM and connection request.
