Personally my favorite clipless pedals I have ever owned have been my Look Keo Sprints, however I havent and probably won't put them on my fixed gear. I enjoy them because they offer excellent power transfer and they're light. I use those pedals with shimano's tri spd's theyre carbon-soled so they arent good for walking so normally if I am wearing a bike shirt ill put some flip flops in my rear pockets and lock the shoes to my bike. If I didn't do this I would probably get MTN bike shoes and pedals as they are more like sneakers with cleats and are absolutely fine to walk in. That's my bit of rambling, but definitely get the clipless they improve your riding so much. As for the trackstanding I am absolutely terrible at it, so I just unclip and rest one foot on the ground(on my fixed gear I have some shimano pedals that on one side are platforms and the other is clipless so when I start I have a base to pedal with before I clip in so its not too slow to not trackstand with them) Hope this helps some!
