Just install an LTS kernel instead of the latest one. Unless your hardware was made literally yesterday you'll be alright, and the number and frequency of updates isn't far from, say, Ubuntu at all.
Also use archfi. It's a super easy and reliable way to get an Arch install going.
Arch used to be a lot scarier. I used to only use antergos because I did the manual install once and was content with not doing it again.
But antergos went away so when my 2014 chromebook stopped getting updates, I did a manual install on there. I had to switch to an LTS kernel to get anything to work but the manual install feels like 1/2 the steps the process used to be and really streamlined.
Also don't be afraid of arch breaking. 90% of the time when something breaks on arch, just go to the arch front page and there's a post about a change that needs a small intervention and exactly how to fix it. These days, ubuntu breaks way more often and harder than arch for me. I still cant get audio to play right on my work laptop after upgrading to 20.04.
