Apple manuals give instuctions for old model Macbook Pro

Apple does not make manuals for specific devices. It makes the manual for the operating system the device is running.

In the case of a 14" MacBook Pro, I linked to the current and most updated user guide for macOS Monterey.

That will apply to your Mac entirely.

The section titled "The Basics" should cover most general things for your Mac.

If you use the search option there, you can find most things. In case of the double clicking of the mouse, entering "mouse double click" results in this as the first result: link-> Change mouse tracking, double-click, and scrolling speed on Mac - Apple Support

..There may be a few new things in this 'MacBook Pro Essentials' user guide..

Welcome to MacBook Pro Essentials (Table of Contents) - Apple Support

Could be some remedial information ~ for most to become more familiar.

Often enough a newer Mac (like older examples) has a fairly good

built-in 'Help' viewer. And seldom find difference in google alphabet

that won't be found within results from Duckduckgo, 'anonymous'

searches; when you can customize your questions, and drill down.

There are more specific online product manuals, however those may

not be updated; depends on where you go looking. ~ Offline, used to

be a better-bet; with "Missing Manuals" by David Pogue, etc. Could be

included with an older Mac; at time one donated a semi-retired Mac.

Those 'Essential user guides' used to also be in book form; a free download.

I've some for iPhone, iPad, Mac mini, etc. Good for use offline; with second

Mac to reference information to fix a broken second Mac. The more useful

link online, that would get superseded, are portions of 'Table of Contents.'

[macOS User Guide is linked along with others, inside Table of Contents.]

Hardware & software resource references, both offline & online are helpful;

& perhaps more so, should those references not change between versions.

<< It should come with its own manual. >>

Apple Macs have always prided themselves that Macs do not require detailed Hardware manuals. Once you know how to operate one, you have the gist of how to operate them all.

You are already grousing about 263 pages, not all of which is directly applicable to you. MORE detail does not appear to be the answer.

There are many articles available that address specific concerns, and Readers here are eager to help you with any specific problems you might encounter.

Just describe your specific concerns, and Readers will be eager to provide more insights.

Up to date instructions for what exactly?

And, it's not the hardware you need to familiarize yourself with as much as you should the operating system - that is what makes a mac work. And there are online manuals for them.

That issue would NOT be addressed with any hardware manual Apple could possibly produce.
