Current trends in capacity planning and oversubscription

While the answer is always it depends, I was wondering what the current 
rules of thumb university network engineers are using for capacity 
planning and oversubscription for resnets and admin networks?

For K-12, SETDA (http://www.setda.org/web/guest/2020/broadband) is 
recommending:

- An external Internet connection to the Internet Service Provider of at 
least 100 Mbps per 1,000 students/staff
- Internal wide area network connections from the district to each school 
and between schools of at least 1 Gbps per 1,000 students/staff

How does that compare with university and enterprise network rules of 
thumb?
