Hello All,
Thank you all for your patience and understanding. 
As an update, the business planning team confirmed that the response that I provided in my 2nd snapshot is the CELA approved statement.
This statement was taken from pg.62 of the NCE Handbook under " Licensing compliance":
It looks like "users" & "licenses" are used interchangeably and mean the same in this case.
Microsoft reserves the right to a tenant limit of 300 provisioned licenses across the Business family of plans.

Thank you.
So, to summarize on the Business License limits, it looks like Microsoft do not want us to provision more than 300 licenses collectively across all Business subscriptions. Meaning one should not have 200 Business Premium and 200 Business Standard (= 400 total = not compliant). However, in the current FAQ and screenshots in previous posts "17.2 - License Compliance" it appears Microsoft is still allowing this as an exception for now, though this may change (Warning to all). That clears that.
Then to summarize the mixed Defender for Business/Endpoint issue between Business Premium and M365 Enterprise... my understanding at the moment is nowhere does Microsoft explicitly state you cannot have a mix of Defender for Business and Defender for Endpoint P1 on the same Tenant, irrespective of which of these two Defender products you have enabled Tenant-Wide. Microsoft does state they "recommend" moving to Defender for Endpoint when you exceed over 300 devices (As DfB is designed for less than 300) but that's about all I can find:
https://learn.microsoft.com/en-us/microsoft-365/security/defender-business/mdb-faq?view=o365-worldwide
Where it gets trickier is if you decide to enable Defender for Endpoint P2 on your Tenant, then it seems you absolutely cannot have Defender for Business licensed devices. The devices must all be licensed with P2 or you can license and configure a mixed mode between P1 and P2 if you don't mind the headache of tagging:
https://learn.microsoft.com/en-us/microsoft-365/security/defender-business/mdb-manage-subscription?view=o365-worldwide
https://learn.microsoft.com/en-us/microsoft-365/security/defender-endpoint/defender-endpoint-subscription-settings?view=o365-worldwide&tabs=mixed
If someone can confirm my understanding of the Defender limitations above when mixing Business/Enterprise that would be great.
And just remember kids, if you're using Conditional Access or Identity Protection or Defender for Office P2 you have to either license adequately and align things further or configure exclusions. Basically, if you provision just one M365 E5 on a Tenant that has other bundles (BP, E3) without add-ons aligning to the E5 modules then be prepared for a lot of compliance or configuration shenanigans it seems. But this is a bit more off topic 🙂
