Here are a few things to keep in mind:
The bikes you mention above are all good choices "on paper" but until you test ride, you have no way of knowing how well they will suit you. I can't stress enough the value of test riding as many bikes as you can! The type of motor, the number of gears, cadence & torque sensors, a throttle, the number of PAS levels all make a huge difference in the way a bike handles. The best bike is the one that you are comfortable with and may not be the one recommended by someone else. By all means listen to the advice of others but make your own choice based on what works best for you!
Finding a bike with everything you want is next to impossible. Most e-bikes use a variety of standard bicycle parts & accessories. Things like tires, seats and handlebars can easily be changed to suit your needs.
The number of bikes available these days with rear suspension is somewhat limited. This is especially true for bikes designed for upright riding. Unless you do a lot of off roading on rough trails, you could probably use a quality suspension seatpost instead. Products from Kinekt, Redshift and Thudbuster are all excellent at smoothing out the ride. Keep in mind that these suspension posts require around 4" of seat rail to seat tube clearance. Check your measurements before buying,
Looking for a bike with an upright riding position also limits your choices. Many bikes can be easily & cheaply modified with a stem riser and / or handlebar change. If you go this route, make sure there is enough slack available in the control cable & wiring harness to allow this alteration.
Whether you carry a spare battery or have it built into the bike, you are still riding with the same weight. Bikes with integrated batteries can be difficult or impossible to remove for transport. this means you have to lift the weight of the bike & battery when loading onto a rack.
The range published by bike makers can be deceiving. Maximum range is determined mostly by battery capacity and the amount of effort you are willing to contribute. Any e-bike will have unlimited range if you do all the work. For the average rider, a very rough rule of thumb is 14 watts per mile. A 48V, 15ah battery will yield 720 watt hours. Divide that by 14 and you can expect to get around a 50 mile range. Things like wind, bike & rider weight, efficiency of the bike motor and slope & surface conditions all come into play but the 14 watt / mile is a good way to estimate a bike's range.
Most e-bikes I'm familiar with are reasonably waterproof. Excluding complete submersion, most are capable of handling rain or a gentle washing. I've been transporting my three e-bikes on an open rack thru many rain storms for 3 seasons now and have not had an issue. It is always best to check with the bike maker for recommendations however. In my case, I cover the display and controls with canvas sleeves to keep out water, bugs & debris. I remove the battery and cover the contacts. I also remove the seat and cap the seat tube to further reduce the transport weight. My bikes require no other protection. The subject of waterproofing has been discussed here many times. You might try doing a search to find ideas for protecting a particular bike make.
One of the major considerations for me when bike shopping was future parts & service availability . Sticking to a major brand with a brick & mortar nationwide footprint is the best way to deal with these issues.
These are just my opinions. I'm sure others will chime in with other good ideas & suggestions.
