Is there an official (re)source where is list it all the categories of commands with their respective set of commands?

Just being curious: **Question** * Is there an **official (re)source** where is list it all the categories of commands with their respective set of commands? Something like [Linux Foundation](https://www.linuxfoundation.org) for [Filesystem Hierarchy Standard **FHS**](https://refspecs.linuxfoundation.org/FHS_3.0/fhs/index.html) I did do a research on Google with the linux types of commands search term but appears few information. But at the top from AI Overview is shared as follows:

...

Navigation: 
cd: Changes the current working directory.
pwd: Displays the full path of the current working directory.

...

Networking: 
ping: Sends ICMP echo requests to check network connectivity.
ssh: Provides secure shell access to remote machines.
wget: Downloads files from the web.
curl: Transfers data using URLs.
