I love apple and any fruit tree is probably good. I use hickory and mesquite sparingly because I find too much can make the meat a bit bitter in a long smoke. I've only used a bit of pecan, but I quite like it and, as with fruit, you can probably use most nut trees, but I have my doubts black walnut.
I think a great use for prunings is wood for the smoker. I've used maple and sugar maple, the latter being quite nice. I would be interested in tasting the difference between sugar maple cut when the sap's flowing and when it's not. My dogs always chewed the wood bits when I tapped the trees.

In TX I used mesquite & oak because that was available on site. More options here with hickory, oak, maple, sassafras, & pecan. I tend to use oak to control the heat & smaller amounts of the other woods for flavor. If I had to pick just one as best it would be mesquite.
Argue for your limitations and they are yours forever.
Post oak. I usually knock the bark off to get a cleaner burn.
I don't mind a little bit of cherry as well, but I don't put nearly as much smoke on my brisket as I used to. If I'm cooking with charcoal, I will put some cherry on the fire for the first hour or so, and then really back off the smoke. There is enough smoke from a clean burning charcoal fire to give you a nice smoke ring.
Too much smoke and it starts to taste like an ashtray.

And for my part, I shall not wholly fail in my task if anything that passes through this night can still grow fairer or bear fruit and flower again in days to come. For I too am a steward. Did you not know?" Gandolf
I have used Pecan, Oak, Black Cherry, Apple, Hickory, Mesquite, and Peach. Which one depends on what is being smoked. I really like a Pecan /Cherry mix when I do a Boston Butt for pulled pork.
St. Louis Spares are usually Oak with a little apple or cherry. I tend to go with Pecan or Hickory for poultry.
