Books I’ve read about backpacking, like this one, usually have estimates for walking speed, caloric intake, and some other hiking-related estimates for average people. Maybe see if one of them has a decent bibliography?
I've read through the Common Mechanics section. It's, frankly, not good, and expecting money for this is quite ballsy.
>Abilities represent the core aspects of a character. The higher numbers represent what the character excels at whereas lower numbers show what the character struggles to achieve.
Assuming someone did not know all this already, how would they know about numbers in the first place?
As an idea on how to these better you might want to look at Design Patterns of Successful Role-Playing Games (pdf). The document is quite dated by internet standards, some content is obsolete, but the general approach is sound.
For an analyis about what Moves are in terms of PbtA games, I wrote down some thoughts here.

I use Obsidian.
Do you have specific pain-points? Do you have areas where you feel your current system isn't working? What are your goals?
Sorry I don't have more specific advice. I've been keeping organized for long enough that I don't know where to start.
Even ignoring what your system may or may not do, a "standard" mechanic for our table is to run a game of Microscope as our session 0 and use that for our worldbuilding. With its palette mechanic, we can incorporate the key ideas the GM or players might have about what they want in the next campaign.
One of them we liked so much that the GM is turning it into a Fate setting he plans to publish, eventually.
Here is a link to my work-in-progress document, several sections are nonexistent or placeholders really, but the core of the rules is there.
The best value in layout IMO is Affinity Publisher. It's $50, one time, no subscription.
It is absolutely professional-grade, and while InDesign may have more tutorials and a bigger ecosystem, if you have the whole Affinity suite, I would argue the tool integration is vastly superior to the Adobe suite.
You can try it out yourself with a free demo.
But software isn't the answer alone - you need to study design and typography at least a little to get a good idea what you want to accomplish.
