I can speak to my own experience as a regular e-bike rider in my city which has built one basic bit of infrastructure that's dedicated to micromobility.
I've been commuting on an e-bike for the past year, and I've recently ordered a replacement e-bike with newer technology (https://www.rohloff.de/en/products/speedhub/e-14). I have racks with waterproof panniers mounted semi-permanently. I pack my work clothes and laptop in bags that I can easily slide into and out of the panniers. I use an StVZO light powered by the bike's battery pack that illuminates the path in front of me effectively while respecting oncoming people.
I live in an American city that built a 10-mile rails-to-trails crushed gravel "linear park" about 8 years ago, and I've been commuting on it by bicycle since it opened, at first on a non-electric bicycle. It's about 10 miles long, and I ride the entire length of it every day I go into the office.
The trail's cost to develop and maintain is a fraction of what it cost to build and maintain infrastructure for vehicular traffic. I haven't been able to find any reports of injuries from collisions on the trail. It's quiet and peaceful to ride along. The air is mostly free of emissions from gasoline motors, tires, or brake pads. The only "road closures" have been due to work on roads that cross it. There is never a traffic jam. There are no stop lights or stop signs, only crosswalks where motorist traffic stops for me as soon as I get to them.
Once I get downtown where I work I never have to worry about traffic, since I can bypass it in the bike lanes. You have to pay a lot to park a car near my office, but I can stow my bike in a locked cage for free. If I want to combine my commute time with cardio time all I need to do is switch off the motor, pedal away, and take a shower once I get to the office. If I instead just want to get there without needing to change clothes or anything I switch on the motor.
There is a shopping district about 2 miles from my neighborhood that's often congested. There's a quiet street and a raised trail through a shallow lake that I often take my e-bike on. Trying to navigate the parking lots is a nightmare with hardly any parking and near-constant gridlock on busy days. I zip past all of that and park at the racks directly in front of the entrance to the stores. I don't get bags at the store, but instead transfer what I buy directly from the cart into my panniers.
Maintenance on my e-bike is a fraction of maintenance for my car. I have sealant in my tubes, and that's made the occasional puncture a non-event for me. The space that the bike takes in my garage is almost negligible. It's light enough to hoist up on a wall hook. I charge the removable battery pack from a 120v outlet.
If something were to really go wrong with my e-bike, I have another much less expensive meat-powered bike with a rack that I can transfer the panniers to and use while I get the e-bike repaired.
My workplace has a sensible WFH policy, where I come into the office a couple of times a week for in-person collaboration and can WFH the rest of the time. I check the weather forecast for the week on Sunday and move in-person meetings around to days when it's going to be nicest. If I really need to go in on a bad weather day, my bike has full-size fenders, and I have shoe covers, gloves, and water-resistant clothing that make riding in the rain not so bad. I still prefer to ride on the trail in the rain rather than drive my car mainly because traffic tends to be worst on those days.
My own quality of life has benefited immensely from an e-bike and a single relatively inexpensive gravel trail that my city converted from some old railroad tracks. As more people discover the joys of e-biking, I hope that translates to more pressure on municipalities to build infrastructure that makes micromobility more safe and comfortable for everyone.
