Take into consideration that lift kits etc do not make any difference to your diffs ground clearance height.
It remains exactly the same as stock.
Tyre profiles change dramatically in any wheel height specs too!
And this changes the clearance height of your diffs + ride height.
A very over looked scenario.
And a taller tyre will " generally " give you a softer ride feel and more forgiving over pot holes etc.
If you step up from say 17" wheels, to 18" wheels, yet keep the exact same profile series tyre, you will gain a 1/2" inch of the diffs ground clearance and ride height.
But... it will throw out your speed etc due to ratio.but Thus giving you a better top end ratio/ speed/ economy.
But you will loose a bit of acceleration performance, and down lown grunt.
Its a bit like changing your ring gears from a 3.55 to a 3.08 etc.
As a general rule...
If you fitted a steel bull and winch, you would need a 1" lift kit to balance out the ride height up front to stock.
So if you had a steel bull bar and winch (100kg) and wanted a 2" lift on top of that... you need a 3" lift kit, that will bring you down to a 2" lift kit to stock height.
But you are really now changing the geometry of the drive line.
Even if a legal with a 2" lift, you need/should make further adjustments to compensate such.
The 1" extra lift kit to compensate for the bar and winch is common, and balances out, and geometry stays basically the same without any dramas.
You have to ask yourself "what is real to you expectations wise"
Rear suspension...
If you are towing a camper van/ caravan/ heavy box trailer the majority of the time, yes heavier duty springs are the go to maintain level stock ride height.
If you are now and then guy...
Go air bags when towing!
Years ago before towing vans and heavy trailers became popular, good 4X4's generally had long travel soft suspension to give a nice ride over the rough.
Sports cars had hard firm suspension, sacrificing comfort over performance.
My opinion is look up what is the max wheel and tyre height combo you can run legally.
This will keep your geometry correct, increased fule Economy , better diff ground clearance, ( lift kits do not increase diff clearance) stock ride comfort feel .
Downside is speedo will need recalibration, loss of grunt down low, but better top end speed equally.
The combination of both wheel/ tyre height and lift kits are taken into consideration as the same when dealing with legal state laws and insurance etc.
So check before proceeding with mods.
If you don't don't tow heavy loads, and don't have a steel bull bar/ winch etc. And not concerned about diff clearance, and you want to keep the softer stock ride feel...
And just want to jack it up a bit..
You can get rear shackles longer, and coil spacers for the front etc.
This will lift the body/chassis only, not the diff height clearance. Handy for creek crossing and looks only.
And keep the stock suspension ride feel.
But it will affect the geometry of the driveline . $$$ will need to be spent to compensate for such.
In essence, a 4" lift kit dose not change your diff height clearance off the ground at all.
Thus leaving you with exactly the same height as stock with axel ground clearance
