Managing black locust in a small space?

A tree that I believe to be a black locust volunteered near the back of my 1/4 acre urban yard. I let it go for a few years because I thought it was a different woody legume I had intentionally seeded (false indigo) before noticing that it was trending more tree than shrub, and making a correct ID (well, I'm about 80% sure I got the ID right this time). Now I'm trying to decide whether to kill it, or if it can be of use to me. Considerations:

It is pretty close to an apple tree, which I don't want it to shade out or compete for nutrients, but on the other hand it could be a good companion if it could fix nitrogen or help the apple in some other way.

It's right on the edge of the driveway, so other than the apple it's not competing with much else or getting in the way.

It's growing through our hog wire fence, so I'm not sure I want to let the trunk get super thick...? Or I guess it could be like those cool old trees that have grown around barbed wire. Right now the trunk is probably a little over 1 inch diameter.

Because it's a small urban lot, and I don't want it casting a bunch of shade, and it might be rude to let it drop a bunch of seeds into the storm drains, I'm confident I don't want to let it reach maturity.

Small urban lot, so I definitely don't want to deal with a ton of suckering, especially not far from the base. Suckers will just have to be removed, so they do me no good.

What do you all think? Keep it or not?

From my non-expert searching, it sounds like the science isn't totally decided on whether non-nodulating legumes share nitrogen with other plants the way nodulating ones are believed to. But maybe if I engaged in a pollarding plan, the fine roots would periodically die back after the stems were cut, providing nutrients to the soil that way?

Can I get anything useful out of this by pollarding it in a fairly small space? I don't know much about coppicing and pollarding so I can't tell how much wood I should expect or how thick/long it would be at harvest. I could use firewood, or garden stakes, or fencing materials. I don't have any cows to feed it to, nor do I want to bother with chop & drop when I can be dropping other plant mulches that don't have nasty thorns attached.

Are there any other approaches other than pollarding to put this enthusiastic volunteer to work?

Living mulch ... chop and drop.
Even fruit trees get pruned heavily.

I just let things grow, but maybe that's just me. there are probably more trees cut down every day than are planted. the world can always use more trees.
but I can understand the idea of managed urban landscapes. yeah when I lived in a suburb with 80'x120' lot my yard was a jungle that some people disliked  cuz like maybe I wasn't "keeping up with the joneses"

My neighborhood is pretty tolerant of unconventional yards, so I don't have to worry too much about looks. But on a small lot like this, I feel that everything needs to be pulling its weight. If I let the black locust get big, it's using up space and sun that I could be growing fruit or something with, so it needs to be offering something else instead. Even the things that aren't providing me direct benefits are still evaluated for usefulness—if I were prioritizing wildlife value, an oak or hackberry probably beats out locusts in my biome, so if I wanted the general benefits of a large tree, I'd probably plant one of those instead.
