What's the best way to learn piano without an in-person teacher?

I recently bought a keyboard and am going to dedicate 30 minutes a day to practicing piano. My goal is to be able to play my favorite songs (jazz & indie mainly), improvise, and generally be competent.

I also want to learn how to sightread, so I've been using https://sightreading.training which has been really useful! I have a background in music (guitar, mostly) and know music theory as well.

Unfortunately due to COVID, Delta, etc, I am not really interested in in-person lessons at the moment, so I was wondering if any tilde users had advice about learning to play through resources online or books!

I'm also really interested in any tips that anyone may have!
