Do lots of test rides. Try different frame styles ( stepthrough city bikes, tourers commuter, MTB) and drive systems ( factory middrives like bosch, shimano and cadence hub drives on cheaper bikes).
Once you zero in frame style and drive system do longer ride eg 2hours.
With ebike you will typically ride faster lot further and for longer so it needs to be comfortable.
Don't over look small things like mudguards, racks, cafe wheel lock and lights they do make a difference. Much like electric windows, remote locking and AC in a car. Allow for extras in budget eg pannier bags, better suspension seatpost,quality locks.
If buying another ebike for sponse, then try to have compatible batteries. With factory middrives like Bosch or Shimao this should be easier as quite often same batteries are used from city bikes to high end MTBs.
