What Pino has said is sound,you probably don't want to start putting on masses of new growth now this close to the end of the season,otherwise you risk having lots of fresh green growth going into winter and depending on your winter frosts that might result in the softest new growth dieing.
This tree has already grown a lot in 1 season by the looks of that new wood as its lignifying and also it has produced figs which takes a lot of energy.
The way nurseries treat their trees is different from the home grower,they have an idea of what they want to sell you,and in this case they want to sell a tree brimming with fruit irrespective of where they are in the season because they sell well and because they have the resources/fertilisers/cover to do that.
That being said the fruit are quite far along,id just water consistently to promote the figs to ripen steadily(bloom boosting fertiliser with high PK) and try to give the plant as much sun and warmth as you can and you might get ripe figs,depends a lot on what our unpredictable summer does in August/September.
If size is what you want then you need to up-pot it and hit it with heavy nitrogen fertiliser next season and keep that up throughout the season,pick of the figs when much smaller than this as this tree has already put a lot of energy into those now,and if you want height rather than breadth maybe trim to 1 main stem(in winter,then you can root that and you have 2 trees for the price of 1) until it's at the height you want and then encourage that stem to branch.
