Chop chop chop???

I got this fiddle leaf from FB marketplace a few years ago. It was my first ever plant in my new home. It was already tall to begin with but it grew at least a foot over the past 4 years. I wanted a tall plant since I had decently high ceilings. Now that I’m learning more about this plant and I’m on this Reddit now, I need advice.

It gets some sun, maybe not enough but this is the sunniest part of my house. Should I chop? Let it keep growing? It randomly gets new growth. I do tie up the branches to the windows so the plant stays more upright. Is that a sign that I should just chop? I wish the trunk could grow thicker but I read that I need to shake it up a bit to mimic strong winds.

I experimented and for the first time propagated another fiddle, but haven’t planted it yet.

One day when we decide to renovate, I’ll probably turn this window into a much larger one.

Thank you!!
