Didn't the Allies have naval superiority in the channel? Couldn't we have just parked some battleships a few miles out, and just shell the crap out of the first couple miles in? And do it for a couple days?

And I'm sure there is some reason we didn't, some rando guy on the internet in 2021 just didn't think that up. But I've never heard a reason why.

Naval bombardments alone never worked on small islands in the Pacific. D-Day’s five invasion beaches comprised a lot of geography. The Allies did not want to telegraph the landing sites.
