Agree with nitass, don't use failover port. A number of limitations and basically no worthwhile advantages

I'd use both 1G interfaces that are already populated with GbE SFPs for HA, configured as LACP Port Trunk. You will need more SFPs for data though.

Observing the ports available, you cannot evenly allocate remaining ports for segregated client-side and server-side LACP bundles. So I'd bundle 2x 10G interfaces as LACP port trunk for data, and use this 20G link for both, client-side and server-side VLANs.

Here's summary

2x 1G interfaces directly to other unit for HA functions. Config sync, Network failover, Traffic mirror
2x 10G to network switch stack. All client-side and serve-side traffic
Mgmt to network switch (ideally dedicated management switch). SSH and HTTPS (GUI)
