Hi again,
Further to the above here are some links with other options for you to consider should any of them appeal to you.
Spa Cycles
In addition to the Ti options mentioned above there is also steel options with either the Spa Aubisque or alternatively the Wayferer

If you interested in them there's a fair bit of info on them in this forum:-

Temple Cycles
The Temple Cycles Adventure Disc could fit your requirements. Also with Temple I think that a degree of customisation is available if and if that's of interest I'd contact them to ask about your options to get it built up as you want.

There's also a video featuring the Adventure Disc on this page:-

Kona Bikes
With the Kona Wheelhouse having been mentioned above there are also other bikes from the Kona range which could fit the bill.
There are several models in the Rove range including the ST steel model but there are also aluminium framed ones as well.

There is also their Sutra bikes:-

Surly Bikes
Some of the Surly bikes might be suitable and I think that they are available as either complete builds or frameset only so as you can build it up yourself. Potentially their Midnight Special, Straggler or Disc Trucker bikes could work for you.

The Light Blue
One of the bikes from Light Blue could work and I'm not certain but their bikes might also be available as a frame only.

Fairlight Cycles (
https://fairlightcycles.com )
Depending on your priorities any one of the three Fairlight bikes could work for you? Also their bikes are available as a frameset only as well as complete bikes. I might be doing them a massive disservice with this overly simplistic (and potentially inaccurate) summary of their bikes range but roughly you have the Faran which could be described as a tough, versatile bike capable of touring as well as much more. There is the Strael which is I suppose what sometimes gets described these days as an "all road" Bike (whatever that means to people) but if you need an example of that bikes capabilities it has been ridden to victory by James Hayden in the last two editions of the Transcontinental across Europe unsupported race. Then there is the Secan which is capable of off road gravel riding as well.
Here's a review of the Strael 2.0

Plus a review of the Secan:-

Although maybe the Faran could be right for you? It's a multi purpose, versatile, go anywhere bike which is built with comfort in mind.
https://fairlightcycles.com/faran
It features the mounting points for mudguards & rack plus I would say that it's designed for comfort not speed as it's not a race machine with aggressive geometry.

It appears to be a well thought out bike and if you read for example about the paint finish on the bike the do give the frame treatment to try and protect it which is done to varying levels by other companies but sometimes falls short of the mark.
For me personally, and this is probably why my next bike will a Fairlight, one of the biggest appeals of their bikes is the fact that they provide two different sized versions of each frame offering both a regular and a tall version. Now although I've been cycling for a long time I've not had many bikes in that time and so I didn't know lots about bike fit and geometries when I bought one of my bikes. Despite the bike shop recommending the size to me I've never got on with it and discomfort problems are exacerbated the longer the ride.
I've since come to realise that for my body shape and style of riding (primarily everyday type riding with commuting, getting to shops and then occaisional longer rides including audax) I'm not personally a fan of a long stretched out riding position with a stem slammed low on a short top tube because I personally find it uncomfortable.
Fairlight have a principle called Fit Form Function but basically what the Fit part of it means is that they offer both a regular and tall version of each of their frames meaning that their bikes will provide a good fit to a greater number of people. The following video does a far better explanation of the idea than I ever could:-

http://fairlightcycles.com/why-fairlight/fit-function-form
And you don't have to be an expert in order to figure out which frame size and version (regular or tall) is correct for you because all you do is select the model of bike that you want from the Fairlight website and then you can enter both your height and inside leg measurement and it will recommend which frame is best for you.
However if you look at there Instagram page depending on whether you want the frame right now it will depend on what size you want as to whether it’s available immediately. The reason being is that if you look at one of their recent posts it says that they are due to release an updated Faran frameset later this year and so they only have certain sizes left. You can see this on the recent post about the orange Faran build.

The reason that I've recommended their bikes is because for me personally rather than the particular specs of a bike including the groupset, finishing kit etc., or discount percentage available the most important thing for me with a bike (which I've discovered over time) is the fit and geometry of a bike as well as the functionaility in terms of will it do what you want of it without being a hassle. For example is it easy to fit mudguards and racks to, does it take the tyre widths that I want to use etc..

Depending on your intended uses this seems like a very versatile bike and for example I’ve seen a video of people doing a bike tour of the Western Isles in Scotland whilst towing surf boards on trailers using their Fairlight Faran bikes.
The short film can be seen here:-
https://www.pannier.cc/journal/beyond-the-north-wind-tour-headwindhaters-film-bikesurfing
If that doesn't show a bike being capable of anything then I don't know what does because I'd certainly not seen someone towing a surfboard on a bike before but then maybe I'm living in the wrong place.
However if the Faran does not appeal then hopefully some of the other options above or perhaps something suggested by Spa Cycles if you speak to them might appeal.
Good luck on the search for the right bike for you!
