digressive or progressive? maybe linear?

I've been doing some reading on this subject and it seems like a very complicated puzzle especially given that the factory setup has quite a few limits.

Currently I'm running bilstein 5100s in the front at the 2nd notch to level out the truck. Rear suspension is completely stock, and it seems like the leaf packs are starting to fail. I know the factory leaf packs are shitty to begin with but mine is now starting to sag and the leaf packs which are typically flat are starting to bend downwards. Probably from all the abuse I put them through. I have a softopper on the bed, no spare, and a sleeping flatform that weights maybe 50 lbs? So not a whole lot of weight on a daily basis. When I go wheeling I'll pack on an additional 200 lbs max. I'm a light packer.

Initially progressives seemed like the ideal match for beach driving, and washboard trails. However as I'm getting more serious about this wheeling stuff I'm encountering a lot of rocky trails. Granted it's not rock crawling persay to the scale where you need a buggy, but trails of various size rocks ranging from 10-20". I recently went to AOAA in Pennsylvania, and despite running 15psi in my tires, and traveling between 0-1mph my truck was getting thrown all over the place. I had a couple of encounters with rocks grabbing my crossmembers as well. Would progressives be a good choice still? I'm thinking with the softer valves the truck could bottom out and grab rocks on the frame a lot easier. I've read that lifting these suspensions causes you to lose down travel. OME seems to make shocks with long travel that compensates, but I'm not convinced if they're the ideal shock. I dont mind getting armour to safely scape on rocks all day and I'm going to get it either way, but if I could avoid the scrapping that would be nice. Are there other kits that allow you to lift while getting extra down travel so the overall suspension articulation isn’t screed up? If a budget limitation didn't exist what would the ideal setup be here? Aside from the 5100s bilstein seems to make a variety of shocks, 6112, 5160, 5165, 8112. Are all of these “digressive”? Are there fairly good setups that don’t require going all out? To be quite frank I dont mind paying the money for kings or some of the other big players but this subject is more than I can chew and I dont want to just throw a ton of money at something hoping it works. I’ve read basically every tech article on accutune off-road which helped quite a bit, but I have to say, they did a disassembly off icon shocks which are “digressive “ and they found them to be linear. So I’m at a point where I don’t know if I can trust what I read based on what the manufacturer says and I’m hoping people with real world experience can chime in. I'm already running 33s and I regeared to 4.88s for them specifically so I'd like to keep bigger tires off the table for now as far as ground clearance is concerned. I’d need more lift anyways for bigger tires.

TLR For rocky trails, washboards, and beach driving what would your premium suspension setup be? What about a mid level suspension setup(i dont mean mid travel)
