The jack of all trades is master of none. It's hard to say this will give you any useful information. When considering a tire, the concept around it being an e-bike isn't as terribly important as it is a bicycle with the possibility of it being ridden faster and further. With that in mind, traction and dependability (flats) might be key things to consider.
However, your ebike setup could just be something to help you over hills or you might ride a lot of thrilling rough trails with sand and loose dirt. The tire one man is going to use will be useless for another.
I am currently using schwalbe marathon plus. I ride mostly paved road and carefully/slowly on anything else. I've never gotten a flat in my area on a non-ebike with kevlar belted tires, but I certainly don't want to try and change a flat on some place with an ebike. I'd probably be fine with using schwalbe marathon supremes or a similar tire but I always go the route of over kill in a goal.
