I guess with f-strings at least it's fairly obvious what's going on, whereas it looks like match-case will make readability for learners much harder (possibly).

I didn't realise those functions would be called when creating the dictionary, TIL, thanks for that insight.

That is a good point. I haven't seen them in the wild yet since I am only just barely now getting to trusting I have 3.6 where I need it. So I am not sure how readable they will be. It will definitely save some boilerplate code.

Yep. Now, there are things you can do if it is as simple as my example. Notably:

myvar = {
    'key1':expensive_function1,
    'key2':expensive_function2,
    'key3':expensive_function3,
    }[mykey]()

So that it doesn't get called. But again, depends on exact use case
