Plus if you look at one of the videos (the Adevnture Disc video from the link below) from Temple Cycles and the terrain that they use their Adventure Disc bike on this could also meet your requirements:-

Reading your message about the position you want means that I would be trying to get a ride on as many bikes as I can before purchasing, although i do appreciate that is easier to achieve with some bikes compared to others. Then if you've either already got or have had a bike with a geometry that you get on with and want to get something similar to you'll have something to compare to. Or perhaps one of the bikes you try with have geometry you like you'll be able to compare that to the other options. There are people will have a much greater in depth knowledge about frame geometry, angles etc. than me but I'd be paying close attention to things like reach, stack, head tube length as well as other factors whilst you're looking to get the position you want from this bike.
To be honest I think that geometry is as, if not more important, than the spec & components on the bike because it doesn't matter how good the finishing kit is if the bike doesn't fit or isn't comfortable over the terrain that you intend to ride it on you won't feel happy riding it.
Also you ideal geometry can be influenced by many factors including your style of riding, the type of surface/terrain but also your body type/shape, flexibility etc. If you watch the Proportional Geometry video from the Fairlight it shows how body type can effect the frame geometry that is appropriate for you.

They actually offer two version of each frame size with a regular or tall version available so it's more likely that you'll be able to get a frame that fits you well. Even if you don't have bike fit data to help guide you to the right frame for you if you pick a frame from their website and put in your own dimensions it will recommend a frame size as well as guide you to the regular or tall version with additional reference to your riding style preference, e.g. race or more relaxed/upright. I could be totally wrong though but if you're not going a custom frame route I don't know of too many other companies offering two versions of each frame to try and offer their customers a better fit.
Happy bike hunting!
