I'm late to the party but I use my Trek 820 as a combo commuter/grocery getter and have not had luck finding a front rack/basket that works with my front suspension (though I haven't really made a dedicated effort yet).
For now, I've settled on just using the rear rack with pannier bags combined with a saddlebag and a big frame bag.
It's not quite as versatile as my ebike with 50liter pannier bags, but I am still regularly impressed with how capable a cargo bike it is despite being an old singletrack MTB.
If you find yourself struggling with front cargo options, it might be worth swapping to some sort of touring fork which can support not only a front rack/basket, but bags on each side of the fork as well.
Good luck and I hope you'll keep us posted on your progress!
