Well, you need to be patient for fig trees.
Don't worry, my rooting skill was even worse, Last year, I paid $200 to buy cuttings from Harvey, All fail.
This year, I try rooting with inexpensive cuttings, I have about 65% successful rate, It takes time to learn.
Beside more Sun light, I think that your fig trees need more, Just like other fruit trees, Fruits are leftover processed nutrition after feeding roots/leaves/branches, you may think about that give them good spring fertilizer, like cheap local worm casting or MG fertilizer, Then at Summer, lower nitrogen fertilizer like Tomato fertilizer or Fruit trees fertilizer.
I find couple good fig trees for our low heat area, I am reducing varieties, It is too much work to take care of them, I need 30 min daily to water them.
Here are couple varieties grow well here, Thinking to put them in 55 gallon barrel soon.
Look forward to see your picture of figs next year.
