First thing is probably that it just works. My hardware tends to be a little cursed, and on other distros I'd often get some weird graphical and system bugs. Manjaro + KDE made everything easier for me. Not sure how I can explain that, it's really just personal experience.
The Architect Installer taught me a bunch about how Linux works and is good prep if you're trying to learn how to install Arch.
And, since Manjaro is based on Arch, you also get access to the AUR (Arch User Repository) where you can pretty much get every program that isn't already in the official manjaro repo (on the condition that someone from the community has created a package for it).
There's no need to use the Architect Installer, you can simply grab one of these , that come with a built in installer similar to Ubuntu. I was merely mentioning its existence because I find it's a cool way to learn.
Manjaro is a pretty mainstream distribution so every program that can reasonably be considered "standard" will likely run on it. LibreOffice and Firefox are popular free software so it would be harder to find a distro that can't run them.
If you're ever in doubt about a certain program running on Manjaro (or really any distro) you can just google the name of the program + the name of the distro ; you will usually find either a way to run it or an alternative.
As mentionned before, Manjaro has access to the AUR ; I cannot stress enough how helpful this is. There really is a lot of software that's been added on there by community users.
One last thing, Manjaro uses pacman as a package manager. So the process to install and update software will be a tiny be different than, say, on Ubuntu.
What's good about Manjaro? Why do you prefer it to other OS?

Do standard programs (libre office, keepassX, chromium and firefox etc.) run on Manjaro? The installer sounds pretty advanced tbh
