I have had the same experience. Don’t run random commands from the internet, don’t install anything that doesn’t come from the distro vendor (a few very notable exceptions can be made for things like Docker if you really must), don’t mess with configuration files, do upgrades their way. Generally speaking you will have zero problems. Sometimes they will do something like switch from one network manager to something like netplan but overall that stuff is trending towards ease of use, not complexity. If you install the newest versions of whatever from random repos or compile stuff yourself you are very likely to mess things up. But nowadays there is very little reason to do that. And you can pick a distro that releases at a pace you are comfortable with, so you have choices.
