That's a good point. I used to have a ceramic coated cast iron pot. That thing was great for making soups and sauces. It was old as fuck though. It came from my grandma. The coating all started wearing away and I eventually had to stop using it. The shitty aluminum ones I replaced it with suck so hard by comparison. I hate them. They don't even boil water properly.
For sure, good cast iron is always fantastic, coated or not! I very much avoid any and all aluminum in the kitchen, including foil and utensils, as it very easily leeches into foods, especially any acidic food will eat away at any aluminum cookware and foil.

Aluminum serves absolutely no function in the biology of the human body while at the same time competing for the same chemical pathways the human body uses to absorb essential minerals like magnesium, calcium, iron, etc.. As such even with a good and balanced diet aluminum can make you lack essentials you are consciously making an effort to include in your diet.
Aluminum cookware is genuinely to cookware what margarine is to butter, basically satan. And just like margarine exposure to aluminum is pretty bad for the body long-term with it being to linked to its own series of health issues. In aluminums case, neurological issues like Alzheimer's, dementia, hormonal issues, and some cancers. etc..
The human body is also not that good at disposing aluminum, especially as you age and kidney functions keeps lowering. Tons of companies sneak it into lots of foods, cosmetics, and some drugs.
The classic trick is of course that each and every product is considered safe for daily use on its own.
However, when you fry your breakfast in an aluminum pan, use a deodorant and/or cosmetics with aluminum every morning, unwrap aluminum foil from your sandwich during work lunch, boil your dinner vegetables in aluminum pots, maybe boil water for your evening tea in another aluminum pot, and take necessary prescription drugs with aluminum in them, you are very much setting your long-term health up for failure.
