Some Norway Maple cultivars are more invasive than others. The main problem with them though is that they release allelopathic chemicals from their roots which inhibit the growth of other native plants, trees, and fungi.
The previous owners planted a bunch of them on our acreage here and they're also really annoyingly brittle vs the native maples. They get damaged in storms easier. I'm constantly cleaning up from them.
I'm currently resting my legs on a coffee table made from the trunk of one that came down in a burst storm some years ago. It's a soft maple but quite nice for wood working.
Just biding my time until the natives I planted next to them grow up a bit more and then I will take them all down and get them milled up.

My street is lined with Norway Maple and barely any seedlings at all come up.
The Siberian elm next door and oak down the street end up with many more seedlings in the yard than the maples.
I can see it being a different situation in a yard adjacent to a stand of more natural trees though.

I lost a number of shrubs planted under one before I thought to look that up. I am plotting its demise even now.
