When i'm troubleshooting something weird/infrequently used, and the explanation given in the handbook is inadequate, i usually turn to the Arch Wiki.
I started trying out Linux with the usual Ubuntu / Linux Mint distros, but I got so confused by the lack of structure and understanding of what is the correct way to do things - aka what I wanted to understand with Linux, for personal knowledge.
I moved to arch, and ease of use came free: everything you'll ever need is basically on the wiki, no weird PPA to add, nothing on sketchy tutorial sites - just the wiki. Definitely suggested for beginners (yeah the installation can be a pain but it's minimal compared to the advantages)
The handbook feels... like a proper handbook. It's got structure and is very comprehensive. The first time I installed a non-Windows OS was FreeBSD as a teenager using only the handbook (I had no internet connection). In hindsight it was an amazing learning experience.
The Arch wiki is more like a compendium of arcane knowledge regarding Arch Linux and a lot of Linux software. It's a lot broader in scope but it can be a bit overwhelming when you don't know exactly what you're looking for.
Compare for instance the entry for OpenSSH in the handbook vs. the Arch wiki:
https://www.freebsd.org/doc/handbook/openssh.html
https://wiki.archlinux.org/index.php/OpenSSH
The FreeBSD page is a lot shorter but it's also more beginner friendly IMO. It ignores the more advanced features and niche use cases to get the user started. If you want to go deeper than that you're supposed to go look for the full documentations elsewhere (man pages, info pages or... the Arch Wiki for instance). It's short and focused. The Arch Wiki page on the other hand tackles many other advanced features of OpenSSH but I fear that a complete beginner might find it a bit overwhelming.
The Arch Wiki is priceless though, it's become my de-facto resource for projects that don't offer good quality first party documentation.
I think it's a depth vs. breadth thing. The Arch Wiki covers significantly more topics, and a vast number of these topics are deep enough to solve your problem or get the job done.
I think the FreeBSD handbook often tries to be "complete" in some sense.
I would put an * next to your statement.
It's more like a user-friendly model airplane kit. It might be overwhelming to a large majority of beginners who would start off better with an RTF model airplane.
As an example, very early in the installation guide you will be choosing EFI vs BIOS boot which you might be able to handle, but not everyone.
To be clear, Arch is my preferred distribution.
