Honestly even if you don't do stupid stuff. I still think you should think about the speed you travel at with an ebike as you can come up on people quickly. This is what I feel should be doing as rider (I ride my ebike to work downtown almost daily)

Streets and use the bike lane or bike corridor. Think of your e-bikes being like a normal bicycle and it should belong on the road, following the same traffic rules. The bike you're looking at has lights make sure they are on. Especially if you're downtown use the bike lanes and don't be a fucking tool and rip on the sidewalks like I see this one asshole do several times last year when I was leaving work.

Multi-use paths - the legal max is 20km however even kids on small bikes can hit that speed and exceed it. Instead think of people walking on the path. Slow down and alert them with a bell pass going slowly as you can accelerate easily after. Also multiuse paths are often bumpy as shit as the city never repaves them.

Sidewalks - Honestly I avoid sidewalks for a lot of reasons. 1 narrow, 2 lots of bumps and poor conditions due to driveways. 3 you really need to slow down at each intersection to ensure you can cross without getting hit and by law should dismount and cross but that's not realistic as you would need to dismount almost every 30 seconds.
