It's not just about runway length. Noise reduction would also make it easier to use smaller local airports. Electric aircraft are already more quiet, but there's probably room for even more reduction by using ducted fans or toroidal propellers.
We may also see a return to more of a hub-and-spoke model. Fly from a smaller, local airport close to you. Fly to some hub near the half-way point, switch to a plane that takes you to a small airport close to your destination. If planes are smaller maybe security can be relaxed too. Total time spent travelling could be comparable to taking a direct flight with a large international airport further from your origin and destination. Then the aircraft doesn't need to be very long range.

The thought of a return to more of a hub-and-spoke model sounds like a total nightmare. It'd take a huge price difference before I'd consider that, personally (EDIT: As in, I usually check "direct flights only" or equivalent and only relent if the cost is ridiculously much higher). Then again my perspective is being near multiple large international airports, so maybe that might appeal to some.

Hub and spoke is primarily used to fill large planes. If you have 10-20 passenger electric planes you'd land at some random county airport, eat a hamburger or a taco while the plane recharges, then get back on the same plane and finish the trip. So you'd have a layover like hub and spoke but all the concerns about missing connections go away.
Exactly. In the EU, Eurocontrol (European Organisation for the Safety of Air Navigation) says 30.6% of flights in 2020 were 0-500km, roughly within the range of the Eviation Alice currently. A further 43.6% of flights in the EU are between 500 and 1500km.

Not only. Gate capacity and runway capacity is an issue too. But that might also be easier to resolve with smaller electric planes. E.g. there's Liliums approach of vertical takeoff from little more than a helipad-sized platform, but even non VTOL planes capable of taking off from short runways would be helpful.
