In terms of FTP/progress, etc. I’m in a similar boat to you.
I decided to go with the LV plan, and to sprinkle some more rides here and there.
What is important, if you want to progress, is to make the hard days hard and keep the easy days easy.
Doing too much too quick will result in overtraining. So, try to keep to the plan, maybe LV would be better to start with, so that you can have your outdoor ride on top?
For the hills, change your cassette. Get something that suits your profile, so that you can ride in your 'hood.
