I’ll add my vote for SPDs. There’s a wide range of styles so you can choose the single- or dual-sided version that works for the bike and use you need. And there are a lot of shoe choices as well. From super light and stiff XC race shoes to way casual and walkable that almost doesn’t look like a bike shoe.
I would recommend against riding clipless on your commute until you’re comfortable with them. Getting stuck in a pedal and falling over, or forgetting you’re clipped in, and falling over, have much higher stakes when there’s traffic. Especially at intersections where you’re most likely to have trouble, and drivers are least likely to be accommodating.
