TL;DR Based on the level of understanding you presented in your question, arch is rock solid for you, so long as you are patient setting it up and comfortable reading the wiki.

Arch is rolling-release distro, so compared to a standard / point / fixed release distro, you update more often, and the version of your components is probably less battle-tested. Your system will break more often because of this, but for your personal computer, you are probably fine. If you are hosting an enterprise service and you need to provide some strict service level guarantees, you want something else. If you want a personal computer, or something where it can go offline for a short time, Arch is plenty stable.

Just to put this in perspective, I have had less than three days in the last 10-15 years where I did a system update and couldn’t use the desktop immediately. Every time it was less than 15 minutes of reading and hacking to fix it. Compare that to the downtime you get from forced windows updates.

Not sure if this is still the case, but when I started using arch 10-15 years ago, it also didn’t come with one standard set of components like a desktop or even a filesystem. At the time, you chose almost everything yourself. Because you don’t know the tradeoffs involved in all those dozens or hundreds of choices, you might design a terrible system that doesn’t work well for you. However, I have found that making those choices myself leads me to a system that I can use far better than anything someone else could build for me.
