There are many to chose from that offer many different options. When choosing a lens you need to consider many things. That list will include:
Budget - how much have you got to spend?
Focal length needed - what are you shooting?
Mount - PL? EF? Nikon F, MFT?
Sensor size - this affect the FOV and the size of the image circle needed to be produced by the lens
Speed - as in aperture. Do you need a fast lens to shoot in low light to create very shallow DOF.
Build - do you need a cine lens with focus gears. Do you need a lens that does not breath when focusing.
Etc
Excellent advice, and I would expect nothing less from Adam, but he missed one simple thing, lenses are your best investment, cameras come and go,
but lenses will always be your "Bread & Butter" investment in the realm of cinematography.
Renting is always an option, but owning them is all about the Pride & Joy of being a smart investor, Especially when you get the chance to brag about them to a future potential client.
Just my 2 cents, Buy, Buy more, and own it!
