The cablecos I've dealt with have a list of modems they let you use.
Since you have to give them the modem's serial number so they can
provision it from the head end, they can enforce it. Here's Spectrum's
and Comcast's list:

That too, but if you're somewhat technically competent, your own modem
and router is generally a better deal even if you have to replace the
modem every few years. You can get reasonable modems for $100 on eBay
or at big box closeouts, $150 to $200 otherwise.
