One must be careful about this mindset. A bunch of smart lightbulbs that are individually operated aren't a particularly appealing target either. However, in aggregate... If someone can write a script that abuses security flaws in them or their default configuration ... even though you're not part of a big centralized target, you are part of a class that can be targeted automatically at scale.
Self hosting only yields better security when you are willing to take steps to adequately secure your self hosted services and implement a disaster recovery strategy.
To add to this, self-hosting is also best when you minimize everything - limited service, with limited functionality, on dedicated hardware that doesn't share access to your internal network or storage. Folks who use point-and-click apps to install a half dozen unauthenticated docker containers, all open to the internet, running on the same PC they store the only copy of their family photos and music/movie collection on... make me crazy.
