Last, if I got an adjustable upper arm I’d assume I could adjust camber but then that’d make the oem lower spring arm worthless right? Couldn’t I lock out the essentric bolt there?

A lot of these bolts are TTY, so they're only good for a single use.
I'm not an engineer, so I won't purport that I know the reasons, but I'm sure it's a lot more expensive to make adjustable arms, not to mention they'd be a PITA to deal with at the factory. Keeping the adjusters, let alone the fasteners sometimes, can be a PITA if you don't torque them right, and even then, they can start backing out over time. I got these arms to eliminate deflection and try to keep the suspension from getting out of control under extreme acceleration events. I didn't say they're necessary, but I was trying to eliminate a problem I was having. These did not do that, per se, but I feel better having them.
They are noisier though, and for many, that could be an issue.

You've already started this, but I'd continue to find feedback from what others have posted. I can't see your signature, but thought you had a ZLE, so you're already good on cradle bushings. Depending on how serious about controlling the diff' you are, and what you're willing to tolerate with NVH, but you might look into diff' bushings.
I honestly don't see a lot of people posting about control arms for strip work. Maybe I've missed them. I don't know that I think they're necessary at my power level, and general purpose, but I think if you've got more than I, and if you're on sticky tires, whatever the activity, I tend to think replacement arms should be seriously considered. But - being the way I am, and because of the issue I was trying to eliminate, I'm happy with them. They didn't fix my issue because they weren't really related, but I know the suspension articulates better and is free'r of bind. I know the arms won't deflect as much, and know, from the past, that rear arms just help settle the rear a lot better. I replaced the rear lower arms on my 4th Gen with poly'arms, and it was night-and-day when getting into a sweeper with expansion joints. They car would skitter toward the outside with the stock arms (only 10K-miles on the odometer) and with the poly-bushed-arm, didn't get upset at the same sweeper in the least.
Your mileage will vary. I feel better knowing they're there. Each time I drive the car after the install, it feels more and more confident.
