I have tried and failed to find substantial research as to what books are good at what ages for children. I have a one year old and will soon have another. Any advice? Most of the books I see are just ads by sites just pushing for clicks and referral revenue.

There are a lot of studies indicating that the mere presence of plenty of books in the home contribute to increased reading abilities and interest in reading. Any advice regarding the migration to e-readers?

There was a study by Pew Research indicating that interest in reading starts to taper off at 9. Any recommendations to help prevent that?

There was another study done showing that parents stop reading to kids once their kids start to learn to read on their own. Are there substantial benefits regarding continuing the practice after the kid learns to read on their own?

Are you aware of other organizations similar to Dolly Parton's Imagination Library (For those who have kids, I highly recommend).

EDIT: Also recommend the Open Dyslexic Font https://opendyslexic.org/ for those struggling or know someone struggling with Dyslexia.
