Thanks for the rake suggestion. I've seen them used successfully, but I am pulling them manually to try to remove as much of the roots as I can (and it's been so stinking hot, I don't mind spending time in the water lol). Cutting requires several cuts over time to "drown" the roots, if I'm not mistaken.
While cattails do help filter the water, like all vegetation they release the nutrients back into the water when they die and decay (nitrogen and phosphorus mainly). When they die off, they can actually cause some level of oxygen depletion. Obviously that is an extreme case, as cattails don't negatively impact all the water where they are occurring naturally, but it can happen.
I don't mind how they look, but it is "swampy" in the cattail areas due to the vegetation decay and old stalks that are poking up from the pond bottom. That combined with my mosquito problem is why I am looking for alternatives. I'm just having trouble finding something that isn't a shoreline plant - I want something that grows in a decent water depth to provide cover for minnows, frogs, etc.
