This makes sense if weather is the main focus. For things like cooking Celsius is great though.

I am failing to understand why there would be a distinction. They all seem arbitrary set points you learn.

450F vs 230C does not feel like anything gets easier there. Maybe in some highly technical baking there are some nice deltas that appear?

Aren’t you just remembering specific numbers though? Unless you’re trying to boil water unseen so that you can only see a thermometer, the specific 100°C mark isn't that useful.
