Are they? Most consumer, even office gear still is maximum 1000M/port - your average USB-C network/multi-port laptop dongle, most USB-C/TB monitors (and shamefully, Apple's Studio Display which only has USB-C/TB ports, no network), VoIP phones (hell these are usually 10/100 only, with 1000 being reserved for top models), printers, virtually all entry to mid range NAS systems... the list is endless.
Options for more than that tend to be really niche, expensive, or are bring-your-own-module-SFP.
Besides, 1000M is way more than enough for almost all consumer and office needs. Only exception is heavy video and photo editing, if these workplaces don't already use direct Thunderbolt/FC attach.
They definitely aren't, no idea what parent is talking about. They are the standard unless you're talking about a SAN or something. If I had to guess, 92% of the switches in a typical office are 1000M, 5% are 100M, and the rest are > 1000M for switch interconnects or HA server interconnects/SANs.
You failed to mention the big one: most people by very far have 1 Gb/s network switches to... Connect their machines to this thing called the Internet. Some may have heard of it.
And most people also have not more than 1 Gbit/s up/down.
Do I have switches (with a 's') with 10 Gbit/s SFP+ at home? Yup. Is 1 Gbit/s obsolete: definitely not.
1gig is starting to become a problem - we have increasing deployment of 2gig and 8gig internet to homes in Poland for example, figuring out how to deal with that when most computer gear still comes with 1gig is becoming an issue
