Im about 168 and body fat is about 12-13%
Do not get lp85's until you get a drysuit you are going to be severely overweight to the point where it will feel scary. Lp85 shine with drysuits not while diving wet unless you are bringing a keg to the party. I have a pair of lp85 and when i dive wet even with tanks at 250 psi on both I am still overweight.

I have found that I can use no lead with 2 AL80s and a razor harness in fresh water, but that's with a 3 mil suit and a well-used 2 mil hooded vest. That's also with a sizable canister light, 3 back up lights, and the assorted crap that we bring with us. I just would think that a 7 mil suit would be much more buoyant. But, obviously you've tested it out and it works for you, so that's great. You will definitely be negative in steel tanks, there's nothing you can do other than wear more neoprene.
In Mexican caves we adjust weight for freshwater because by the time you hit the halocline, you're deep enough for some suit compression. Still, I tend to 'bounce' off the halocline in sidemount a bit if I'm not prepared. For some reason this is more noticeable in sidemount than backmount.

Im with you on that I dive wet primarily and I’m stationed in Florida, love diving dry so I’m finally making the investment. What dry suit are you looking at? When you dive dry with the lp85 do a end of dive check cause the cave fills up here are super negative and heavy but at end of dive the raver steel are neutral.

I dive an LTZ with 35 pounds of lift. In a full 5mm and 5/3 hooded vest I use no additional weight, except for lights, backup mask, dsmb/reel, etc. I have never felt overweighted even with an al40 for deco. I have OMS lp85s. But even with 3442psi hp100s I am fine.
For comparison, in a full 3mm with a single al80 on SS plate I use 4 pounds. I’m 6’2” and 220lbs. Not as lean as you but not by much.

That's entirely a matter of opinion. I routinely dive a Worthington LP108 with a wetsuit or just a skin and I LOVE it. In fact, my profile photo is me in a skin only with the lp108 (first Key Largo trip after I was certified).
Just make sure you have enough wing lift to handle the tank. I haven't looked up the characteristics of the smaller lp85 but I have to believe it's more buoyant than the 108.
