I ride a look system, but that is for a road bike. The pedals require cleats that are difficult to walk in.
SPD pedals work pretty well. The cleats are metal so they do not wear out. The cleats also allow you to walk pretty well. Also, SPD pedals can be had relatively inexpensively. I think that using SPD would be a good place to start. Once you get used to clipless, then you can try other things.
Here is a caution. Nearly everyone has an embarrassing crash with clipless pedals initially. What happens is you go into a stop, you forget to unclip. So here you are stopped and still fastened to your pedals. You manage to get your foot out but by then your weight has shifted to the wrong side and you are slowly tipping over the wrong way.
One way to prevent this, is to practice clipping in and clipping out on a short tool up ride. But you will probably forget to do it anyway.
It may be that I was already used to toe clips or that I was mentally prepared for it, but I did not have this problem when switching to clipless.
