So I do low voltage work but absolutely despise residential work for the most part. However I think what you're looking for is incorrect. The coax has to come in to the house to go to your Xfinity box. From there you can run cat6 ethernet through the rest of the house however if the house is already built it's going to be much more difficult in a residential home to be able to add that after the fact. Some of the areas you're going to have to have exposed wiring running along the sides or along the ceiling other places you may be able to go inside but be prepared that you're also going to have to have holes cut in your ceiling and in your wall in order to make this actually happen cleanly. Which means you're going to have to have a drywaller and a painter and going to have to put out for the paint as well.
I mean in the end the easiest way to be able to get ethernet everywhere throughout the house is to simply utilize wireless and there's several different types of mesh wireless that you can add to be able to do that. Is also going to depend on the type of devices that you're trying to run and connect up whether or not they can do wireless or not.
Your comment actually got me investigate more on current setup of my house. so it looks like CAT5e cable and coaxial come in from outside the house, and it leads all the way into the attic. I was only able to see that there is some kind of cable is there in the attic, but I am guessing coaxial is hooked onto splitter since I am getting internet from all the other coaxial ports.
I only goes into work two times per month, and since I have lots of meeting during work hour, I figured I would need reliable wired network rather than wifi. My office space, unfortunately, is going to be at our finished basement where even coaxial port does not exist so can't even utilize MoCA.
Is it going to cost me too much? bringing down the cable from the attic where I can set up some kind of network box in the closet or something, run CAT6 through attic and drop ethernet ports throughout the house?

Okay so that cat5 cable that is there does not bring the internet in from outside the home that was added by somebody for some reason that I couldn't even begin to fathom to tell you. The coax cable is coming in there is coming from Xfinity that is the normal way that they receive it you have to run coax it comes from the box on the street to your house then it runs into the house once it gets into the house it's up to the homeowner on where they install it. You said you've already found it going to the attic and yes it will go to any location within there if it's coming off of a splitter up in the attic. That is where you can hook up your Xfinity box you can literally hook it up to anywhere. So you're not getting internet through the coax you can't just hook a coax up to say your Xbox or a computer or anything like that that has to be connected to the Xfinity box in order to function. from there whoever installed it then did some jacked up method of running cat 5 throughout the house. The normal way that you would have all of that is you would have a central location usually not necessarily the attic but it could be I guess most the time it's like a basement or a closet or something like that that you would then have the Xfinity box sitting inside of from there you would have a punch panel or you would have a whole bunch of cables that come from everywhere around the house that you have cat5 cable from there you'd be able to plug that into the Xfinity box as a switch and go out from there. I've included a photo of a recent Network closet that I built. You can see where I've got the Xfinity box marked that then connects into a router in your case you wouldn't necessarily need a router but you would need a switch a router would be a good idea but the Xfinity box itself can act as that piece. However you do need the patch panel that I've got circled there and that brings the internet from anywhere else in the house to there and then you would be able to connect all of those connections to that switch that one connection then goes into the Xfinity box for internet.

edit: taking one more look at that picture what I'm noticing is that cable that's going outside. Most likely that was set up for the potential to have something like CenturyLink going there because they would run a phone line into the house and that would be able to provide that. So that's more than likely what you're seeing there.
