There's some decent spots in Hollywood that would put you close to the beach. You could also look into Pembroke Pines, Cooper City, Miami Gardens (my dad's side lives there and it's a richy rich area for the most part). I lived in Cooper City with my aunt to go to school there, it never really changed. Pembroke Pines keeps getting bigger and bigger, it's got it's ups and downs. And before moving to Orlando in 06, I lived in Hollywood right off US1. Hollywood is kind of tricky, the closer you are to the beach, better the neighbor hood. Cross US1 (going west) and it's not so pretty, cross Dixie Highway and you think you're some place else (with windows rolled up).
But Hollywood is kind of nice. Back before they rebuilt the horse track we used to go on saturdays for a $5 concert, usually 80's bands or some group really outdated. The beach was about 15 minutes away, and we'd go to the intercoastal and grill up some burgers. Y100 (radio station) used to do their annual concert at Young Circle Park in Hollywood, and they've done some major revamping on it. Hollywood is also known for it's arts, there's a couple different Playhouses. There really is a little bit of something for every one in Hollywood, but it's a very mixed bag of people.
Ohh and you'll have to try Jacksons, it's an Ice Cream parlor on US1 with a line out the door most nights. Very small, but very good.
Just avoid University Dr, Flamingo Rd, and Pines Blvd and main roads to the job. They are the worst and heavily traveled during rush hour. But almost all the streets run in a grid, so it's a bit easier to take a few side roads.
