I haven't kept up with the latest e-bikes (that aren't for gnarly mountain biking), as I have my commuter/errand-runner and no need for a replacement within the next ~5 years. I do have a separate e-MTB as well, and it's great for the trails - which I can just bike to. It'll get me around town too, but doesn't have the cargo capacity to be as useful for errands.
Generally, I think Class 3 e-bikes aren't allowed on sanctioned trails. Of course, that's likely rarely enforced, and I wouldn't personally have qualms with it like I do against e-motos like Sur Rons.
If I had a do-over, I'd scale back from my super beefy ~100 lb grocery getter to something much more reasonably sized, no more than 60 lbs. If I were you, I'd look to something that could augment your current life. If you already don't need to drive anywhere in town and happily bike/transit around, maybe the around town bike isn't useful to you. If you do need to occasionally drive for bigger errands, maybe a bike with more cargo capacity is in order to keep that car off the road. If you're just looking for a fun bike for trails, maybe that's an option, but most e-MTB won't have an integrated light.
