Lately I am using sometimes VS Code and IntelliJ. The VS Code feature of recommended extensions is great for the initial setup of projects.
Is there an equivalent in the JetBrains ecosystem for Plugins?
Are you talking about Workspace recommended extensions (where you can list plugins that are needed for this project or the project/user will gain benefits from having such a plugin)?
If yes: Settings (Preferences on macOS) | Build, Execution, Deployment | Required Plugins

(NOTE; the screenshot is from PhpStorm. IntelliJ IDEA will have it in a similar place)
P.S. On related note: https://www.jetbrains.com/help/idea/managing-plugins.html#suggested-plugins
2023-01-09: Such settings will be stored in externalDependencies.xml
file in the PROJECT_ROOT/.idea
folder (where other project-specific settings are stored). This file (as well as many other files there) can be put under VCS if needed. Check the following links for more info on that:
