I’m in the process of choosing hardware for a 30 story building. If
anyone has experience with this I’d appreciate any tips.

There are two fiber pairs running up the building riser. I need to put a POE
switch on each floor using this fiber.

In my experience with retrofitting existing structures, if you have access to
the riser at each floor as it sounds like you do, you would typically drop in a
new duct,  blow micro duct through it with a branch for each floor, have an
MDF  or two In a utility spaces  and them you have the ability to reconfigure
the fiber as necessary to meet your present and future needs.

You didn’t specify if the existing fiber is single or multi-mode however it is
unlikely that the was enough slack built into two fiber runs to make 30
additional splices so that approach seems dubious as a premise.

As you correctly surmise daisy chaining 30 switches is not an advisable
network design practice.

+1 to that,
Put your own fiber in and do a star topology to an MDF device.
