I used to just use a range, a decent toaster oven and a microwave for most stuff. Heating up a regular oven is such a huge waste of power for a meal for 3-4 people.
When Instant Pot made a countertop oven with an "air fryer" feature, I bought one. When I wore that one out, I bought another.
An oven with a circulation fan is a convection oven. When I worked in a pro kitchen, our Blodgetts blew a hell of a lot harder than any air fryer, but no one would actually say they're frying the food.
To each their own on what they consider things.
