You're on the right track. Creating lift with a combined approach is the ticket. Easy button is to dial suspension lift to the max, but that won't come close to how much better it can be tuned in this manner. It's going to take a bit more effort but this would be my recipe for a high performing LC.
285/70R18 (+1.1" lift)
Excellent choice at 33.7" tall and will still play nice with KDSS. This is going to be the only mod that actually creates more lift under the rear axle. Gearing and braking will still be good, and won't require re-gearing like a taller tire will need. This will create more approach, departure, and breakover as it's not only taller, but the faces of the tire will be further forward and aft. All that rubber will add to suspension and articulation capability when aired down, with more compliance, traction, while making all holes and obstacles smaller.
1" body lift (+1" lift)
Best kind of lift bar none with almost zero drivability and handling compromises. You can tuck the front and rear bumpers up a matching amount to create better approach and departure. There's a good chance you can shim up sliders if you're headed that way too.
+35mm Effective Offset
Either aftermarket wheels or use a 1" spacer with stock +60mm wheels. This will keep suspension geometry and scrub radius just about perfect for the 33.7" tires. Increasing track width for sidehill stability. Less bump steer. While making everything fit easier and with more clearance (than with lower offsets). Sure, you can do +25 offset or a 1.25" spacer, but keeping great suspension geometry is king IMO.
Suspension Lift (+1.25" lift)
While I'm a proponent of less suspension lift, some lift is still good. Add the fact that aftermarket shocks are typically longer adding travel. The stock 200-series keeps most of its travel in droop (5.5") with only about 3.5" in compression. For fast Baja type running, having some more compression travel is beneficial while the added shock stroke maintains down-travel. So something like a 1-1.5" lift is perfect, keeping all goodness of geometry, and reaping benefits elsewhere. IMO, the ticket is Bilstein's with great all around tuning and a slightly sportier digressive valving. It comes with multiple perch positions on the front shock body so a mild lift with the stock springs is possible. Pair that with a mild 20mm spacer lift in the rear. While everyone else is chasing stiff spring rates, the stock tender springs are going to be so good and slinky in the rough stuff. Paired with that digressive shock for better control of the larger wheel/tire and better overall vehicle stability. Sure, if you're going to add gear with lots of installed overlanding weight, you might need more spring, but less is more IMO.
Overall, that's going to stack up nicely to an aesthetically pleasing 3.3" total lift. Even better is that it'll seriously perform in all conditions with factory like drivability and little compromise.
Back on weight, in the words Colin Chapman - Simplify, then add lightness. No less true a principle to off-roading... for performance, capability, durability, just about everything. I'll pay more for gear that is simpler and lighter where possible.
Bonus
Add Durobumps all around if you like high speed running. Will make for plusher and controlled hard hits and g-outs.
