Solution
Add classpath("com.facebook.react:react-native-gradle-plugin") in android/build.gradle dependencies
I found this docs page useful for this specific issue, but it just led to a new issue... The root of my more general issue was that I was upgrading from a lower version of React Native, and had forgotten to include some of the changes needed. The best way to fix these kinds of issues is to use the React Native Upgrade Helper, which will show you exactly what needs to change using a sample application.
