Sorry to be late arrival to this discussion. As stated earlier, I live just around the corner from where you job is and have been here for several decades.
Just a few thoughts, based on your post:
Traffic sucks and it's getting worse all the time. I'm supposing your job is in the Miramar Park of Commerce, on or near Miramar Parkway and Palm Avenue. If so, there's lot of nice, available housing all around. I recommending renting first to get a feel for the region before putting down deep roots somewhere. You can avoid a long commute
If you really want to live in a walkable community, Weston Town Center downtown Miami Lakes and the new Pembroke Pines City Center are possibilities. So is Pembroke Gardens. If you don't mind a 30 to 45 minute drive to work, downtown Hollywood is a possibility too. Just realize the farther west you go, the newer the neighborhoods and the less likely it is you'll find a walk able situation.
Besides the traffic, people are standoffish or downright pushy until you get to know them. Remember that nearly everyone down here is from somewhere else, so there's a lack of civic pride and initial trust. It takes longer to get to know others.
Now the good parts - there's always so much to do and lots of interesting people of all types to do them with, once you get to know some folks. And the weather is the best in the state. The family and I have enjoyed the diversity and the million things to do. It's a great place to be young.
Post to this thread with questions - I promise to check it often in the next few days. Let me know how I can help.
