Best locality in Northern Scottsdale and Phoenix and ways to commute. Moving.

I recently got a job in Desert Ridge, Arizona. I want to move into a locality with a lively atmosphere with relatively young people (mid-20s). I don't own a car right now, but I read that upper Scottsdale and Phoenix have bare minimum commuting ways and are also super costly. I would like some advice on where to stay. My work is hybrid; I must work 3 days a week from the office. I'm unsure if buying a car is the right thing to invest in immediately. Should I get a car and move to a subpar location or stay in a lively location and try to find methods to commute to work? I am so confused, would love some advice
