Good pedals and shoes will have you glued to the pedals like velcro. Flat pedals and shoes have come a loooooong ways from 20 years ago.
IMO, having a large pedal platform that is slightly concave is key. For a reasonable price, I think Deity Deftraps are a great pedal. Really large platform, and a true (though subtle) concave design. Also like Kona Wha Wha 2. Both are around $50-$60. I think these quality composite (platic/nylon) pedals with steel pins are actaully a great development. They are cheaper than aluminum, and handle rock strikes very well.... arguably better than aluminum.
Shoes make a HUGE difference as well. I never really got this until I tried a pair of dedicated flat pedal shoes. I know 5-10s are the most popular go to, but I just got a set if Ride Concept Hellions, and like them a lot.
