Well first off, in franchise mode you can select between a variety of options including pretty much the entire player management aspect set to auto. If you want, you can make it so you don't have to sign, resign, cut, scout, weekly training etc.
There's an option for everything to be on auto, manually or customized. If you set to "simple" (I think that's what its called, could be wrong) you just play the games. Exactly what you're looking for.
I am mainly an offline guy too, I play franchise and play now games. I'm loving this year's game so far honestly. Microtransactions have really no impact on enjoyment. If you wanna buy coins or packs for ultimate team to make your team better more quickly than grinding challenges, that's an option. But you do not have too and if you don't play ultimate team than you'll literally not have to deal with it.
So overall in my opinion, I think the game would be great for what you're looking for. You can just play the games and have some fun.
