There are a lot of great tactics on here. But, please understand how the game works. Even understand how real life football works. There is no such thing as "best tactic". Never has and never will be one. There are so many factors that come in play. One tactic will be good for one team, but for another team, it simply won't work. That is for the game and real life football. What is your definition of plug and play? Just about every tactic on here is set to not need any changes to it. That is the point of this forum, to share completed tactics. So, by that definition, every tactic is then a plug and play. You upload it to your game, you select it and then your job is to assign the right players to the right positions, team train properly, individually train properly and bring in the right players that fit THAT system. Different players fit different systems. What do you think a plug and play is? You upload your tactic and then go on holiday the whole season and everything magical fixes itself? Every tactic is technically a plug and play in the sense that you don't need to make any changes to the tactic, nor need to make in game adjustments. I never had to and I am doing just fine. Can you? of course, but you don't need to. The tactics I use are created to play a certain style, so why am I going to change that?
