I don’t think “most” have fiber to the home, first of all. Cable companies in the US do multigig speeds via fiber to a relay and coax cable to the home. Fiber is great when it’s underground or in a data center and safe, but it is delicate and easy to break the cables so not a great home solution. Fiber terminations are difficult and more expensive. The power efficiency payoff on a 1m cable from your router to your pc is probably going to be measured decades, more if you factor in the higher cost of the cable.
And your pc is connected by fiber directly to the modem? It sounds like not, which was the point of of the parent comment. But you can’t tell me that you think this is a normal and typical use case, to install PCI-E fiber optic network card.
Recognize that your situation is not like most people. Old apartment buildings especially will not be keen to run fibre everywhere when coax can handle gigabit speeds just fine

I have fiber directly into my house. My PC is on the opposite end from the modem. This comment is a load of baloney
