I've been commuting by bicycle for the last 25 years. I've tried just about everything. Sometimes you need a truck and sometimes you need a Porsche. You will learn by experience and eventually, if lucky, end up with both :>). In a nutshell, you need to find out for yourself. But there are some basics that will be helpful to get you started:
1. Get something that fits reasonably well.
2. Get something that you can put a rear and/or front rack or basket on. You will need to carry things. Especially since this is now your car.
3. The less valuable the bike the more likely you will use it to grocery shop and make quick errands; bicycle theft is a real disadvantage. Regardless of value, get a U-Lock and use it.
4. At 5:30 AM you will need, at a minimum, a tail light. A headlight is also recommended. Getting hit by a car SUCKS!
5. Bike shops can be helpful. You will know which one is right for you. Check them all out and don't be intimidated. Be honest about what you can spend and what you need. The bike industry really isn't geared towards practical cyclists like ourselves, but if you are honest and adamant, a decent bike shop will work with you. But unless they have some trade-in's on hand you won't get out of there for $200. But you will learn a lot so do not skip this step! Even if you find something used from a private party start looking for a good local bike shop. They can be really helpful.
6. Steel frames are good. Wide, high volume low pressure tires are good. Handlebars at seat level or above are good. Seats ... well ... that is strictly personal preference, but generally. the wider the seat the more upright the riding position. Racers with the handlebars inches below saddle level like them narrow. A medium width is 155mm.
Most of all HAVE FUN !!! Biking can be life changing.

I should also add that simple bikes are best. You do not need all the latest technology. Keep things simple and learn to maintain your bike. If, after you learn the basics, you decide you want some of the latest wiz-bang stuff than great; go for it. But until than keep it simple and learn how to repair/maintain what you have. For me it is part of the fun.
