In other words, if I order an upgrade to an SPV m500, will the sim card from
it function fine in my Nokia 6021?

I bought the 6021 sim free and put the sim from my K750i in it and it
functions perfectly. I've been offered a free m500 for 50 upgrade fee.
Obviously, it will come with a new sim card, which will presumably have to
be registered.

Will that sim function fine in my Nokia 6021, or are there any quirks of it
being a smartphone sim that will cause it to misbehave in my Nokia?

Si.
