It seems that if you prefer the simplicity of not dealing with front chain ring shifting or have particular difficulties with using multiple chain ring setups, then you'll simply have to decide where on the gear inch range of priorities you lie.
it's pretty much that simple.
As you say, 11 and 12 speed setups have similar percentage jumps between gears compared to 8, 9 speed but again, it's up to you if you can live with the jumps and the range.
A 10 speed deore triple setup has smaller % jumps, even with a 11-36, so you have the black and white knowledge to help make your decision.
happy riding no matter the gearing.
And happy jabbing when it comes to you
