New to custom ROM, I need help - eviltoast

So I have a Chuwi Hi9Air (is a tablet) and I wanted to put LineageOS on it but I have some questions.

  1. I found this guide but it’s 2 years old that makes me install Android 10. I know that the current LineageOS GSI is Android 13, so which one should I install?

  2. If I should install Android 13, here, on the list of Android GSI there are 2 GSI versions (“LineageOS TD-based” and “LineageOS"Light”" ), which one should I install?
