IMO large platform MTB pedals with pins are fantastic for any style of riding, unless you feel the need to be clipped in (which you stated you do not). The bigger the better. My wife and several friends have put the massive Kona Wha Wha 2 pedals on their road/gravel bikes and love them. I have been running a set of Chromag Synth on mine and I just got a set of larger sized Deity Deftraps to replace them. All of these are composite (nylon-ish), which IMO is a really great option these days. All have replaceable metal pins. These are not cheap plastic pedals you may be used to seeing. All are around the $50 price point.

The really large platforms help make up for less stiff soles of non-cycling specific shoes, and the traction pins provide a ton of grip and let you pedal over the top of the stroke and back across the bottom. They give up nothing to clipless unless you are sprinting hard.

I have not used toe clips in 22 years and if I never do again it will be too soon.
