I can comfortably do 50km with maybe 900m vertical riding in EMTB the whole time on my Rail at 75kg. I've not run it completely flat ever. By very rough estimate, I reckon I'm getting ~10% more range riding in the new EMTB-lite mode (gives 140-250% assist). Big days riding planned in Rotorua...
Got my first ride in with this edition of the firmware on my Rail yesterday. Very pleased, had to check I was not in EMTB mode the assistance was so powerful. This will likely become my default riding mode now rather than EMTB other than in really steep, extended, technical climbs.
The Bontrager Connection tyres do not appear to be tubeless ready but you plan to swap those out and Rekons (which are tubeless ready in 27.5 and 29 sizes) would be a good choice.
You could convert the rims to tubeless with the Stans No Tubes tape (or similar from Muc Off, etc.) from what I can...
Not necessarily a SRAM one but definitely one with an XD driver fitment. No other special tools are required that wouldn't be needed for any other MTB cassette, just a cassette tool and chain whip.
I had the same but found it went away by running my seat post just a little lower. Turns out I must have been "rocking" from side to side in my seat from running it too high.
I'd concur with that. I'm 5'10.5" (33" inseam) on a good day and ride a large Rail with very little seat post extension. The large has a 170mm dropper whereas the M has a 150mm but can take a 180mm One Up dropper.

It's still best to try one in store if possible.
Here in New Zealand the two prong type bike rack is very popular (not quite universal, but pretty close).
