I think one major use case in this particular scenario is that the author has one 25 Gbit/s and one 10 Gbit/s internet service. If you want to make the most use of this fibre is the only way to go.
There is no need to have 10Gb in bedroom, such tech produces a lot of noise and heat. Maybe Stadia or similar video streaming could use such bandwidth. But this looks more like wiring for residential building with multiple flats, or office building. Or like some sort of tech flex.
…until later in the home’s life when that bedroom is no longer a bedroom, for whatever reason. If you’re gonna do a project like this you might as well take it to its logical conclusion.
It’s the same kind of advice I’d give to anyone who buys e.g. an iPad Pro - you might not think you need a cellular model right now, but that one time you do need it two years from now you’re gonna be very glad that you paid the extra ~$100.
You cannot take your mantra to its logical conclusion and apply it to everything, everywhere, at least not unless cost is absolutely a non-issue for you.
Until you’re driving, hypothetically, through rural Arkansas, where there's no Starbucks and your iPhone has juuuuuust enough signal strength to receive the WhatsApp telling you that you need to turn around a couple of slides but not enough bandwidth to download the deck.
Your iPad, though, for reasons known only to the black magic gods of RF design does have a stable-enough LTE connection and it saves your bacon with the large corporate client that dragged you to razorback country in the first place.
Hypothetically.

There’s a reason I wrote iPad Pro. It’s not my mantra - it’s advice that applies to specific kinds of people in specific kinds of situations. The kind of people who have the means and motivation to run fiber throughout their house, for example.
