Hi again,
Also if you were to consider a bike from a British company there are two lovely looking bikes from a company called Fairlight (
https://fairlightcycles.com ) and given what I've read about owners of Fairlight bikes who are from all over the world I'm assuming that they ship to the USA. If their bikes appealed to you I'm sure that you could contact them to ask and confirm.
Here's a review of the Fairlight Strael:-

And a review of the Failright Secan:-

Fairlight Cycles (

Depending on your priorities either one of the 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 (but the Faran is currently unavailable). 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 two editions of the Transcontinental across Europe unsupported race. Then there is the Secan which is capable of off road gravel riding as well which includes being able to take wider tyres that the Strael and 650b wheels if you want.
One reason that I've mentioned this bike is you've mentioned comfort being important and unlike many other companies Fairlight make it easier and more likely that you'll be able to get a frame which fits you.
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 'race' 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 (
https://fairlightcycles.com/why-fairlight/fit-function-form/?v=79cba1185463 ) 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:-

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.
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 (which I know are also important considerations for everyone) 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..
I'm not quite sure how the price works out once you've converted to US Dollars but I thought that perhaps roughly say a 105 build might come in within budget and I think that the USD is currently strong versus the pound and so that might help you?
I hope that you find the right bike for you!
John
p.s. your walk sounds amazing and I hope that the last days of your walk go well!
