I have always used Shimano SPD pedals/shoes on my road, hybrid, and MTBs... just like the ability to walk around on all surfaces.
Like Fender or Gibson over in my other obsession (I split the difference and go PRS).
Guess what? My principal electric guitar is a 1979 Japanese Pearl Custom Export. And my current electric bass is a 1978 Greco Electric Bass Both guitars are there.I guess I am Rickenbacker then.
Same with me on the Vado. Too many things to control (including the new dropper post) and I started forgetting about the feet clipped in...I have clipless on both my road bikes and since I like them so much I decided to put a set on my Pedego RidgeRider. After riding for a couple of weeks I took them off and put the flat pedals back on. Not sure why, but I prefer riding my ebike with the flat pedals.
I agree with your recommendation on the composite pedals with nylon spikes... I got tired of giving blood on rides.For something grippy but not dangerous, like a metal cage pedal or mtb spikes, this is a really nice alternative from The Shadow Conspiracy Shop. My LBS gave me a set to deliver my mountain bike, but I ended up getting a pair of Stamp1's, put the Shadows on my crossbike. They're cheap and good - https://shop.theshadowconspiracy.com/shop/parts-accessories/pedals/tsc-surface-plastic-pedal.html
Oh, and the CrankBros Stamps are really nice. A lot of riders on the mtb forums like the nylon pedals cuz they don't clang so bad if you hit something, which seems to be common with trail riding. Already been there done that. Plus the anodizing finish of an alloy material gets scratched off giving them a ragged look. Got the Stamp-1's and really like them so far.
For shoes I've been wearing my RedWing moc-toe work boots with the white christy soles - just outstanding. Perfect grip and protection, easy to reposition a foot, the pedal spikes hold tight. They'll probly be too warm for summer trail riding. Like those shoes @Stefan Mikes .
