I've been OK using a 32 x 11-34 for a few years now, on a couple of different hardtails. Most of my riding is local north downs, Surrey hills area but I've done a few trips to the Welsh trail centres and to Glentress without too much difficulty.
Might be a bit different on a Helius AM in NE Scotland though! :o)

I've got a 2+bash setup on my Enduro, with 24/36 on the front and 11:34 on the back. While I tend to do most things using larger cog on the front I do still find 36:34 too high at times, so if I was going with one cog on the front I'd go 32 with 11-34 on the back.

Personally I'd be a lot more inclined to go 2+bash on the front though, especially with a reasonably heavy bike.

Do you spin or mash? Freewheel or pedal downhills?

I have used 32 and 36 ring with a 11/34 cassette. ( both on commuters) 32 is a bit low - but does give a hillclimbing gear. 36 is better until you hit the steep hills. Try 32 for starters

32 11/34 has served well down here in Surrey as well as GT/Inners and North Wales (did Snowdon, but none of us really rode much of it upwards).

36 at the front. 11:34 at the rear on a 29er. That's a tough ratio and a bigger wheel compared to the others above but I can get up everything locally (purbecks).
I would suggest designing it around getting your easiest gear right as life is easier with a good climbing gear and spinning out downhill. You spend much more time going up so get that aspect right.

I'd recomend 32. i've run 32&36 on a 32-11T.

both were ok although i did end up walking a lot more with the 36t (bike will also be issue with this)

slx also do a 36-12T cassette. (29er specific supposedly)

if you were to run 36T 36-12T caseette would give you a bit more range but not huge.

32:32-11 = 26-75 inchs
36:32-11 = 29-85 inchs
36:36-12 = 26-78 inchs

32 11/34 here too on a 29er. Only ever an issue on silly long and steep climbs like Carn ban Mhor where Id rather get off for a walk than spin a granny anyway.
