From the neighborhood node to the house wasn't replaced? Yes, it'd be transparent to the customer because the neighborhood node would be converting the signal from light to electrical.
Light being immune from EMI, yes, much better signal...that is, if OP had a noisy signal.
Wouldn't the main line from neighborhood node to the tap have to be replaced too? I thought the tap converted the signal. If that's not the case, then wouldn't my neighbor, who shares the tap, and I both have to change our internal wiring if one of us wanted to change to all fiber? Wouldn't Cox have to replace the line from node to tap then? I'm asking because this is your bowl of rice, not mine.

The tap or NID or NIU on your house would only connect to whatever technology of the Internet provider (fiber or copper). It wouldn't convert the signal but accept the signal as is from the pedestal or neighborhood node.
You could change your internal wiring to fiber if you wanted, but you couldn't connect it to the demarc of Cox because Cox has coax connected to your demarc. Since your tap is connected to the pedestal with coax, Cox would be looking for a DOCSIS to authenticate and not an ONT.
If Cox told the OP his or her residence is only configured for fiber, this sounds like it was news to the OP because somebody ran fiber within the residence without he or she knowing.
Yes, if Cox told the OP his or her residence is configured with only fiber, somebody would have had to replace OP's wiring and tap and install an ONT.

Thanks. That’s a thorough explanation. The node converts signal, not the tap.
I knew that if I wanted to convert to all fiber, the line from my house to the tap would have to be replaced. All my internal wiring would have to be replaced and my modem would have to be replaced with an ONT. But, I’m not planning to change my internal wiring for fiber.
I got a bit more confused than usual when you said “From neighborhood node to the house wasn’t replaced?”. When the main line runs parallel to houses, wouldn’t replacing cable with fiber also include from the node to the tap?

I'm by far no expert on this.
Tap. I think I need your definition of a tap. To me, a tap is a coaxial splitter. However, a tap only looks like a splitter because one of its outputs is designed to not degrade your signal. On a splitter, however, all outputs degrade the signal. To me, this is a tap and it would be inside the NID bolted onto the side of your house.
If you're defining a tap as where Cox connects to your house, to me, this would be the demarcation point. At one side of this point is the end of the Cox network (neighborhood node) and the other side is the beginning of your network (household wiring).
I don't know what you mean by "tap."
Cox sends the signal via fiber optic from its headend. The light signal keeps going until the edge of the fiber network. If the edge of the fiber network is fiber-to-the-curb or fiber-to-the-neighborhood, the signal will reach an Optical Network Unit (ONU). This ONU will convert the light signal into electrical, pass the electrical signal onto the coax network and go to your house.
If your house has fiber to the demarc or fiber-to-the-home (FTTH), your ONT will convert the light into electrical for your RJ45-equipped router(s) and gear. With FTTH, you still have a neighborhood node, but it's just a passive device. Meaning, this passive device doesn't do anything except send light signals to multiple houses.
When the main line runs parallel to houses, wouldn’t replacing cable with fiber also include from the node to the tap?
It depends to where the cable is going. If the cable is running parallel to the houses but is bypassing the houses to connect to a neighborhood node, then no. The neighborhood node would connect to the house and not the cable. You can't have hundreds of houses "tapping" onto a main circuit.
If the cable is coming from the neighborhood node and running parallel to the houses, then yes. Each house would strip off a strand from the bundle of strands.
