A few thoughts... The crank forward bikes from Electra and others have a significant flaw in that you are pushing back against the seat. They seem great for a few miles until you realize how sore your back is getting keeping yourself on the seat. Also, aluminum can be quite harsh and hard on joints.

A bicycle with Dutch geometry (Workcycles, Gazelle, Batavus, Azor, etc.) will align your sit bone, back, neck, and head in a straight line which is much better for them and for your comfort. They are designed so that you should be able to tip toe the ground while seated on the saddle. There is very little to no pressure on your hands and wrists, you use your arms to steer not to support your weight. The geometry and fork rake provide for a very forgiving ride that is not hard on your joints.

As to longer distances, I've routinely ridden 60 and 70 miles in complete comfort. Thousands of people throughout The Netherlands and Europe do so every day including many seniors.

For her retirement my wife bought a Workcycles Gr8. She's been quite thrilled with it.

There is a reason that so many people around the world, and us older folk in particular, ride them.
