Honestly, I'd suggest a prioritsation matrix here.

Classify all the tasks with an impact / ease score from 0-5. Multiply the numbers together to understand the relative priority of each item.

It won't be perfect but it will a good place to start.

You also do this at a product level instead, and invest all your time onto one product to begin with. This might reduce your switching costs working between projects/products.
