Nah, DCEU is one thing, Snyder is straight up another. OG Justice League is much weaker than the Snyder Cut's special brand of torture... er, demensia.
In any case, Superman, especially given Snyder Cut amps, probably solos this before the villains can react or really get anything serious going, more or less. The bad guys are tough, but Supes can hit them really hard, a ridiculous number of times. He can even do something silly like put all of them together in the same room or deserted island or whatever. These guys are NOT going to work together. He's too fast, too strong and too tough, IMO.
For the MCU, it will be harder and there will be a LOT more collateral damage, but at the end of the day, I don't think any of the baddies can do effectively anything to Carol and she can eventually get to them. The city is probably toast, given the lack of super speed and because you've erased some of the potent tricks the MCU kids bring to the table, like ring-outs. Thor raining down AoE blasts and autohoming lightning will help, Strange doing Strange things will help. Carol is bringing most of the heat, and it is a pretty massive amount of heat.
