The most broken way of playing a fighter is to not and play a monk instead

The trouble is, you only get one set of Str 23 gloves; so the question is twofold:
1) What are you optimizing for? It seems damage output and nova potential, right? Skill checks don’t matter, Utility spells don’t matter, sustainability doesn’t matter, you just want everything dead in 2 rounds then long rest after? I ask because what’s optimized for one task is not for another, and I can help with a party setup for whatever you want as long as the goals are defined.
2) What classes / themes do you feel are must haves? The optimal party for blowing stuff up may not include any healing at all, but if you want Shadowheart to be an awesome cleric then that’ll be something different, she can certainly be that!
3) Do you just want level 12 builds that destroy things in Act 3, or does it matter to you build order and having them have power spikes early? In some ways being powerful at 4 is as or more important than being powerful at 12.
4) Do you want just one build you build towards the whole game, or is respeccing on the table and if so, how often?
Haven’t tackled this yet just because it seems overly broad at this time, but happy to help, would just love some additional clarity on what’s ideal from your perspective.
