What type of fish is best suited for baking?
To answer your main question, you can bake very just about any type of fish.

Looking at that recipe though, down in the "tips" section, it suggests you use a flaky white fish. So in that category, you have lots of options, snapper, cod, tilapia, for starters. Their flavours are often a little more mild and will pair nicely with the tomatoes and other flavours in there.

If you're prone to overcooking it, take it out sooner. I find many fish recipes that give cooking times tend to get you to overcook it. It'd done as soon as the fish "flakes" fully. Leave it any longer it will start to toughen quickly.
