The bases I create are labeled “External” (even after accepting my Organization's invite) and lack the same functionality as bases created by the Big Boss. Are there currently settings that ensure bases created by users within the organization are internal (and benefit from the functionality associated with our price plan)? Would changing my permissions level from “Creator” to “Owner” make a difference?

I guess I’m confused that a user can belong to an organization, yet the bases they create do not. Put another way, in practice, every user other than the Big Boss is individually on the “free” plan and creates only stripped-down “External” bases. I'm told we're in the process of migrating from Teams to Business. Will that remedy this?
It doesn't make sense to me that only one person has full functionality, regardless of number of users in the plan. I don't have access to the organization's settings. Are the ones with access simply overlooking something?
I appreciate any clarity provided.
