BGP is certainly universally standard.

Anything with BFD will depend on software compatibility on the other side.

EIGRP, as an example, is not standard. So that automatically takes out
customers who do not run Cisco, assuming they are happy running an IGP
with a different AS.

Not being negative, just saying that while an IGP can solve the failure
detection issue faster than BGP can, it opens up other issues you really
need to evaluate. It will be difficult for you to appreciate these
issues until you have experienced them yourself, however.
