The eduroam Policy Service Definition tells us that:

"
Wireless NASs MUST deploy the SSID "eduroam" and MUST broadcast the
SSID "eduroam", unless there is more than one eduroam SP at the same
physical location and the signal overlap would create operational
problems, in which case an SSID starting with "eduroam-" MAY be used.
"

So your chosen name of eduroam-5GHz is at least policy conformal.


It's not very user friendly though and I would first try *very* hard to
get my WiFi behaving correctly; perhaps introducing band steering or
deactivating some of the 2.4GHz radios to reduce overlap in this band
or or or. But this depends very much on the capabilities of your
equipment.


But about the specific use case:

This would only work if you don't configure 'eduroam' but only
'eduroam-5ghz' in the problematic macOS devices. Then these device
wouldn't connect at other places besides your campus. AFAIK you can't
prioritize SSIDs in macOS.
