Even some of the best of those,like here too, shed leaves.
Surrounding trees can be a reasonable gauge.
Sometimes, some of those trees can go overboard on leaf loss and look miserable. And the cause could be hard to identify at times.
They aren't intended to produce fruit, but it does happen. Not really good to eat.
They can be weak.
Look at our hazard tree page at www.mdvaden.com
The top photo is a cross section of one of those. The dark linear areas are trapped included bark due to weak unions. More prolific the past few decades. Some of the older ones were not that bad due to nursery practices.
If you have the weak "v" unions, consider drilling and attaching eyes in limbs facing each other and putting a small cable with clamps in to hold it together.
Its quite easy. Just don't drill too big. You want a tight fit for the threads to anchor in.
If the leaves curl a bit, check for tiny green aphids that cause leaf curl. Enough of them could trigger some leaf loss. Go to a local nursery to see if there is a systemic insecticide - or - call a pro. But if the problem is minimal, maybe you can live without the pesticide use.
Oh, don't eat fruit if systemics are used. In fact, if it does put out fruit in the future, maybe skip the systemics in case somebody unaware of the treatment tries to eat the fruit.
