For the middle option don’t you need the Sony remote to “learn” the codes?
You only have to teach it something that it doesn't do after you enter the code for the Sony. I would almost guarantee the Inteset would do everything for the Sony. There are quite a few other members here who like this remote (check out the remote control threads for Inteset). Best $25 one out there. I used an Inteset on my patio to run a Sony STR-DH510 a few years back for just music, never an issue, without "teaching".
