Could someone here please recommend a good book defending the superiority of homeschooling over classroom schooling?

If you want to go WAY back, this one is interesting. Most of the book is an argument against public school but the alternative presented is Catholic schooling.

John Taylor Gatto & Maria Montessori both have several books that would fit this description. Gatto is more directed at how bad public school is; Montessori is more about best practices for early childhood education.

After reading an article on Maria Montessori in a 2022 edition of The Broken Wheel (starting on p.31), a periodical publication supervised by Fr MacDonald (attached), I wouldn't recommend anything that comes from her. Here is the conclusion of that article:

In conclusion:
I strongly recommend, for those who like to watch videos or listen to podcasts, the conference
entitled “Resistance Podcast 122: The Problems of Maria Montessori Part 1”:
.
I only watched the first five minutes before I wrote this article, but I would have saved myself a lot
of time and research if I had watched it all. A lot of the quotes I put in this article are also found in
this podcast. However, it is very complete and goes much deeper than I am able to intellectually. Do
not be discouraged by the first 9 minutes. If you prefer, go straight to minute 9.
Part 2 is entitled “Resistance Podcast 125: Catechesis of the Good Shepherd: a Wolf in Sheep’s
Clothing”:

This looks like a solid resource:

It's an out-of-print TAN book by Seton Homeschool director Dr. Mary Kay Clark.

I wouldn't recommend anything that comes from her.

Supposedly Pope Leo XIII endorsed her, but she certainly is not a homeschooler. She was the founder of maternity schools (where mothers with their young children would both be away from the home and in her classrooms).

Yes, I do remember Seton's book.  At www.Joyfulcatholic,  also known as refuge of sinners, a book titled "public education". This one will go an angle on Fɾҽҽmαsσɳɾყ that brought the public schools in to teach no God.

That link doesn't work.  When I typed in .com, I was redirected to this:

[Catholic Home Schooling: A Handbook for Parents is an] out-of-print TAN book by Seton Homeschool director Dr. Mary Kay Clark.

Thanks again for this work. I'm only about ⅛ of the way through it, but right off the bat it covers the advantages of homeschooling:
Thomas Nelson's preface lists 8 advantages, pp. xvii-xx:

• "You do not waste the students’ time."
• "You do not re-teach what the student already knows."
• "You can give your own children more individualized attention."
• "You can gear the work to a pace your children can handle and that will keep them interested."
• "You can (and should) eliminate the option to fail!"
• "You can build in automatic consequences for failure to perform."
• "You can emphasize reading."
• "Home schooling eliminates the silliness and nonsense picked up from peers."

and Dr. Clark's ch. 1 (pp. 1-22) argues homeschooling's advantages:

• no sex-ed (indoctrination into ɧoɱosɛҳųαƖity; cf. Fr. John F. O'Connor, O.P., "The State of [']Catholic['] Education," who told parents not to send their children to "Catholic" schools)
• character formation
• academics
• public (& "Catholic") schools "the training camps of the enemies of Jesus Christ and His Church." (p. 9)
• raising "cradle Catholics"
• benefits for the
  
  • student: socialization
  • mother
  • father
  • family
  • community
  • Church
  • nation
