David,
First off, welcome back.
Second, as Matt said in one of our videos, if a program you did worked well, why not use it again?
With that said, after a layoff and a weigh loss, I’d suggest Beginner Acclimation.
You can run it as written, or if you did it before and want some variety, feel free to swap an accessory exercise for similar one.
EG:
Barbell row instead of dumbell row.
