payload in jumbo frame?

Question

Computer networks

Good day! Interested in the question of the interaction of L1-L4 MTU.
Globally / on the interface on the equipment, you can specify the size of the HW / L2 MTU up to 9216 bytes (depending on the vendor). At the same time, you cannot specify more than 1500 on the SVI /L3 interface IP MTU. when routing a packet anyway it will be fragmented into multiple packets with IP MTU value? Then what's the point of jumbo frames outside of a flat network? What is the profit for DC networks in east-west traffic?

Example1. L3 switch
#int gi0/N
mtu <1500-9198>
#int vlan X
mtu <1500-9198>
ip mtu <68-1500>

Example2. [PC1 Linux]<- - ->[PC2 Linux]
#ip link set [int_name] mtu 9000
