I don’t know if this will help anyone in their first place, but I was just setting a family member up with Comcast (only choice) - remember that:
1) you get gouged if you don’t buy your own cable modem
2) you should be calling to (politely) negotiate a new contract annually

I don’t know, here are some other Auntie Lesley tips everyone assumes you already know:
1) adding people onto a family cellular plan is absurdly cheaper in the US than a new account
2) there are small mobile service discounts for everything under the sun from employers to AAA

3) Comcast business costs about the same as XFinity internet in many metro areas and has SLAs in exchange for slightly slower speeds so don’t just rule it out if you’re a cable cutter.

4) Your ISP’s DNS servers- just don’t use them, not even once - there are a lot of alternatives and you should select one based on your threat model because they all have positives and serious negatives
