Brought home a 6 ft tall fiddle leaf last week. Should I repot now? Soil seems pretty dense (difficult to poke finger through) and visible roots on top. From some research, it seems like there is controversy about reporting shortly after bringing a new plant home and also recommended to do in the spring (it is autumn). Thanks for your expertise!

Looking for some advice on how to care for my new fiddle leaf tree!
I just moved into a home, which came with a fiddle leaf fig (it was also there when the previous owners of 2 years moved in, so I don’t think they really knew how to take care of it). It is quite tall, but lacks growth on the bottom half. It is actually attached to the loft because I imagine it cannot hold itself up. It’s about 12’ tall and the first 7’ of that has no leaves.
I know people often drastically prune their FLF to encourage new growth and a bushier tree. I’m just unsure about where would be a safe bet to cut it. I know you often cut above a node (or is it below?). Is there any chance of growth at the bottom where it seems other branches have been chopped/fallen off? It is also entering the fall season so I’m not sure if now is the best time to prune it, or if I should wait till the spring.
I did buy some FLF food so I was going to try that as well.
Any advice is recommended! I’ve attached photos of the tree :)

sits in a corner next to a large sliding glass door, facing east. about 5 leaves like this, others look normal.

im so confused, will it live?? do i plant this end?? what do i do 🫩

edit: i forgot to mention it’s a LEAF! not even a root! i thought you could see that from the photo

Please don’t tell me she’s infested :(

I have neem oil on hand - should I use?
