Southwest newbie - boarding B4… is that good or bad?

So I’m a totally newbie to southwest. I’m going on a work trip and my boss booked me on Southwest. I checked in this afternoon and was given B4.

Is that a decent-ish spot? I will be bringing a small carry on bag, so am hoping I will be able to use overhead storage. I have a meeting like an hour and a half after I land, so I’m really trying to avoid the gate check matter.

My plane is a Boeing 737-700 (idk if that matters lol).
