Help with buying first car as an adult

Title is a little vague but here’s the background. I’m in my late twenties and never had a car. Lived within walking distance to work and just made it work. Finally looking to purchase and I have no idea how the process works at all. I have good credit 760s and I’m not looking for anything crazy (I’d happily do something used as I’m just going to and from work). Yes I have my license before that gets asked. I can’t really ask family they’ve been fairly unwilling to help out in the past.
