Looking for appropriate cisco switch

[WangSteven02215]

As shown in the figure, Catalyst 9500 Switch and log server are installed in Cyber Security Operation Center. I need to buy a switch to transmit syslog in each system, but I don't know what switch would be best. (The place marked multi-layer switch in the figure is where the new switch will be placed) For reference, L2 and L3 switches from various manufacturers such as HP and Ruggedcom are used for each system. Also, the new switch must be received optic signal because of long distance. Could you please recommend switch for this configuration?

Thank you for reply.

You said that if L2 switch is used in system, 9500 would be doing well. However, there are L2 and L3 switch in the system A ~ N. 

I don't know which switch to use because of this reason.

Cat 9200 / Cat 9300 recommended in A and N place, again this recommendation based on the input and diagram, is this what you are looking?
