There’s a study I posted below that says that bike lanes are just about always safer, didn’t really talk about sidewalk riding though. Where I live (not Florida) there’s a lot of blind driveways, so riding on the sidewalk can be dangerous for cars coming out of their driveway. (Second link describes that). Happy riding!

I have both in ear XM4 and over ear XM5s and I don’t like either. The xm4 is just too big and too heavy. It feels like it’s barely hanging onto my ear. I’ve tried using the for running or bike riding and they fall out. If you try to force them to stay in your ear it can wedge itself in too tight and get painful.
The XM5s are too tight and they hurt right below my ear if I wear them too long. The anc is good but I had some Bose QC35s before and they were waaay more comfortable and worked just as good.
I wish I had got the AirPods Pro and whatever new quiet comfort headphones Bose had now. Still thinking of switching.
