Shortlisting colleges based on a specific major

Looking for advice on how to go about researching best schools for a given major rather than completely relying on rankings (major specific rankings) available on US News, Niche etc. Would most of the following information be available and easy to find on college specific websites?

a) pathways for a given major after 4 yr undergrad

b) companies hiring undergrads from a specific major

c) internships and/or co-op opportunities available for a specific major

d) is there is a possibility of doing double major or major and a minor alongside a chosen major

e) student/teacher ratio for a specific major and whether only faculty teaches or it can also be by teaching/graduate/research assistants
