You can use custom project initialization scripts (these are copied into New Project and executed at first launch).

• Press FETCH button to download my ready to use sample init script fromhttps://github.com/unitycoder/UnityInitializeProject/tree/main/Assets/Editor
• Confirm that it was downloaded by pressing [...] button (it should open Scripts/ folder next to unitylauncherpro.exe) and that folder should contain "InitializeProject.cs" file
• Enable [x] Use Init script, by checking that box
• Now create new test project from Projects or Editors tab
• Once Unity editor launches, it should display this init script window: *I have added Hot Reload here manually as commonly used package
  
• Press Setup Project and the initialize script will do your setup automatically (based on my sample script, which currently does these things, listed here:https://github.com/unitycoder/UnityInitializeProject?tab=readme-ov-file#current-features
• After init script has completed, it will delete itself

• If you want to make your own init script, you can modify my base scripthttps://github.com/unitycoder/UnityInitializeProject/blob/main/Assets/Editor/InitializeProject.cs
• You can assign your new local InitializeProject.cs location in that field or add online hosted script URL (and press Fetch to download it)
• NOTE: if you use your own scripts, make sure the NameSpace is "UnityLauncherProTools", Class is "InitializeProject", and Method is "Init"
• You can assign your commonly used .unitypackages in the Init Script window (Click Select Assets). These values are saved into EditorPrefs
