Your post makes sense. If you want control and want to keep one or both parents a secret, then yes F1 hybrid is the way to go. Although often the F1 will surprise you and may not yield the exact traits you're after. For the home grower you'll just need to make the cross enough times to make the seeds you need.
Alternatively, making a cross, following subsequent generations to the goal you want and eventually having a stable variety is easily saved and shared with others. The genetic segregation at the F2 and F3 points (assuming you can grow enough plants) can yield some genetic combinations that could be rather unlike the F1, which may also be attractive (fruit color, fruit size, etc.)
