Here's the US Annotated Constitution if you're looking for some deep reading.
I've been planning to homeschool my two-year-old with my wife so I've been working on a curriculum for a few years. I basically started with the following resources:
CDC Milestones https://www.cdc.gov/ncbddd/actearly/milestones/index.html
These are used as a sanity check to see if you children have developmental issues. In general, you should expect a child to reach the milestones somewhat before the target age, but they give you a good sense of what your child should be doing by what age, and a good list of things you can work on with your child.
Fairfax County Program of Studies https://www.fcps.edu/academics/elementary-school-k-6
Fairfax County is one of our country's premier failing public school districts. If you navigate to each of the grade links you can find another link which will give you a list of objectives for each grade level. For instance, here's the page for sixth grade: https://insys.fcps.edu/PublicPOS/#/reportPanel/6/0
So when you have time you can see the standards by which the students are being measured. I've ripped out a lot of the more asinine standards, added lots of my own, and made notes about how I'll cover the objective when the time comes.
MIT Highlights for High School https://ocw-origin.odl.mit.edu/high-school/
I generally feel that a conscientious and hardworking middle-schooler can do what we consider first-year college work. I've basically started with these courses and added and removed what I thought was appropriate. There's some libby stuff in here for sure but also excellent resources.
Also, FWIW, The Art of Problem Solving is probably the best math education resource on the internet.

I use orgmode to organize my thoughts and JIRA and GSuite to do coordination. I've also written a bunch of pedagogical tools I've used for myself and which I plan to use with my child/children (mostly flashcard or trainer apps, that sort of thing).
I've skimmed "The Well Trained Mind" and I thought the author had exactly my mindset and some excellent recommendations but I need to give it a more thorough read this year and see what I can bring in.
I can talk about this plan all day but I feel like this post is already way too long. If any pedes want to make a more permanent page for homeschooling resources I'm all for it; we might get some use out of it before "eternal september" hits or the shills take over. And if anyone else wants to talk shop feel free to DM me.
