Just to add, I have been told by people who know, that you should always update when installing a new package because not doing so can leave your system in an inconsistent state. Just get into the habit of running pacman -Syu <package-name> or if you use yay, yay -Syu <package-name>

You’ll never get perfect binary compatibility because different distros use different versions of libraries. Consider Debian and Arch which are at the opposite ends of the scale.
