Unit Team structure

Working on a game where I need to manage teams for players and cpu players. It's so easy to try and make everything a component in Unity. I was first thinking of ditching a manager and work with tags. But my intuition says that there still needs to be a place where I manage my units.

As of right now I'm thinking of creating a Team manager which yields "Team" objects.

Team class for now:

 public class Team {
     
     public int id;
     private List<GameObject> units;
     public int resources;
     
 }

edit: added more functions for completeness

Team manager for now( yes it's still a component, simply so that I can add it to my "main" entry point):

 public class TeamManager : MonoBehaviour {
     
     private static short idCount = 0;
     private Team[] teamList;
     
     

     public Team getNextInLine()
     public void initStartTeam(int start)
     public Team createTeam(string name = "" )
     public Team getTeam(int id)
     public void reset()
     
 }

Is this excessive and is there an elegant way of managing teams in Unity?
