I don't really have enough experience with them yet to have specific thoughts but my impression is they are very basic currently and need a lot of work. One thing that's really important is being able to do bulk actions against multiple users quickly. I remember the times when big attacks would happen and we would have a sudden flood of obvious problem users posting comments blatantly intended to cause disruptions, being able to efficiently respond in the moment to that scenario can be really important. It sucks when the mod team lacks the ability to respond quickly because in the meantime users trying to have a real conversation end up getting harassed, angered, and driven away with the impression the mods are worthless. You don't want to have to fight your tools and spend a bunch of time per individual action because by the time you get to dealing with the full swarm of trolls the conversation might have really taken a turn or be basically over so you end up cleaning things up after it doesn't make much difference for the users. Also, bots like automod are extremely useful and important so I would say the fediverse needs them ASAP. I never messed with the bots when I was mod but they were definitely like a force multiplier for the mod team.
