I'm wondering if there's any downside to placing the dryer vent higher up on the wall instead of the typical bottom position. Due to the cramped space in our laundry room, we plan to use a stacked washer-dryer unit like the LG Washtower. By putting the vent hole higher, I could shorten the duct run. I've read that keeping the duct run short and straight is important for preventing lint buildup, and that rigid pipes are preferable, although I haven't seen many people actually use those. Is there any reason not to do this?

I have a long vent that goes up over 6 feet and across another 12 to the outside, and it works perfectly fine for me. No lint issues, plus it dries my clothes great!
I'd say the main focus should be on having a shorter and more straight duct run. While going up higher might seem efficient, lint can accumulate if not done properly. It might be better to consider positioning it in the middle of the wall for your stacked unit if that works for the layout.
Yeah, you can definitely vent it higher! In fact, some folks even vent straight through the ceiling. As long as you're minimizing bends in the duct, it should work just fine. That's what matters most in a tight space like yours.

Exactly. Mine runs up and vents through the roof too. It's pretty common around here, and so far, no issues. Just make sure everything fits well so you don't crimp the duct.
