Turn Base Battle Simulation/Autobattle

Hi everyone, I am looking to basically make a turn base 2D battle system where units will attack based on speed. My team will be made of scriptable objects with stats I set, as will the enemies. I would say similar to final fantasy style but instead of me selecting what my team does they will default attack until they got enough energy to use a skill. Trying to use this for a Idle game. So once i click battle the teams will fight till one team wins. I'm not expecting someone to write it for me but maybe point in a good direction, the tutorials I have found are not really what I'm looking for.

Thanks,
