Because your question is very specific, I will address the home vs online schooling issue.
Because of the pandemic, online schooling has dramatically improved, but also because of the pandemic, staff shortages are affecting its efficacy. Interaction with your peers is a desirable learning tool, and supplementing that with a homeschool curriculum should cover all bases.
Search online for homeschooling groups in your area, maybe a local Facebook page, these people will have information. A good homeschool curriculum will coach the parent in such a way that they won’t need a degree, it will help them to take advantage of resources available.
Fortunately, there is a lot of good info out there, in the last 25 years, homeschooling and remote schooling have become much more comprehensive and doable.
Good luck with this. It sounds daunting to contemplate, but it’s really not that complex.
I speak from some experience..
You’ll do well. <3
