I hadn't experienced something like that either, as I know how to handle a cable. I just wanted to point out that it depends on several factors whether 1 GBit can be transmitted or not.
When choosing the cable (and the sockets), I am a bit confused right now. Do I want Cat5 or CAT7 or something completely different? It is important that I can connect the "standard plug," which is apparently called RJ45. But of course, I also want to plan for the future...

Cat6 sockets have RJ45? So you can replace the sockets later, but have the better cables in the wall, right? What is the difference between Cat6 and CAT6a sockets?

"CAT" or in German boringly "Kategorie" tells you something about the quality of the twisted-pair (aka "network") cabling. Higher is better. The cables are e.g. better shielded and are therefore standardly suitable for higher frequencies = bandwidths. CAT6a is specified up to 500 MHz, CAT6 only up to 250 MHz. CAT6a thus meets the specification for 10 GBit/s transmission speed at 100 meters cable length. Relatively irrelevant for a single-family house because 100m cable length is usually not reached anyway. But since CAT7 cables are standard anyway, i.e. even more powerful, you shouldn't save the last 50 cents on the socket. CAT7 sockets do not exist by the way, hence the recommendation for CAT6a.
RJ-45 is only the connector type and is not directly affected by the category.
