Is there a way to truly do due diligence on that front? Some independent authority that will guarantee available connectivity with a bond or something? You certainly cannot trust the ISPs. Even if their salespeople don't lie to you out of greed, poor tooling, or incompetence, unless there's a working connection already, you run the risk of "sure, you're in our footprint, but we can't physically connect you because reasons" at installation time.
The closest I can think of off the top of my head is requiring a working (and testable) fiber connection before signing, and refuse to close if there isn't one. I have no idea how that would impact trying to buy a home today.
A qualified surveyor should be able to tell you if a fibre line is connected to your home.
Here in the UK at least companies are not allowed to lie about which houses can and cant get service, and there is a regulatory body (ofcom) that regulates this and other telecommunications service aspects.
Just to add (cant edit). They also regulate speed and can receive fines for over promising and under delivering. As a consumer i can raise this with the ombudsman to force action or remediation.
