One rule of thumb is that if the bushing moves through more than 1 axis, poly isn't the best choice because it just isn't meant to flex like that. The big front control arm bushing is one of those spots.
That said, some poly bushings take this into account and work fine there and definitely give you a performance benefit (Whiteline ALK for example). Another option would be STI Group N rubber, or just replacing old OEM with new OEM. And of course spherical bearings but that's not for everyone.
Poly works great for inserts like the diff and subframe bushings and for simple bushings like the swaybar. It works fine for bushings that rotate on 1 axis (rear upper control arm).
I did a broad write up on bushings on our tech instagram page here:

So with that said, I would probably piece together my own kit rather than a complete poly replacement kit. Old worn bushings suck and since it's usually a gradual decay, you might not realize how janky yours have become over time.
