I just use Look pedals on my road bike and I can't fault them. Wife uses it on her bikes so everything im house is interchangeable. They're affordable (as long as you don't want titanium spindles and ceramic bearings), comfortable, pretty light and work well with maybe annual service. Interestingly, third party Look compatible cleats (eg. Decathlon) are more durable and cheaper than Look original ones, although a slight bit heavier.
On my gravel & whatever bike I just use flats with MTB flat pedal shoes . While the powermeter suggests I don't lose out during any sort of constant effort, road shoes are just super super comfortable as the hours go on.
