Hi, Dean,
My name is Didi. I'm happy to help you today.
At the moment, signing up for the Teams free (classic) version seems not available anymore that's why you get directed to the Teams for personal/Teams Essentials despite choosing the For work option.
The only option to get the other apps/tabs is to subscribe to any Microsoft 365 Business plans or try them for a month. You may visit: https://www.aka.ms/office365signup
Best regards,
