LACP is not a "must have", you need it if you want to have physical HA.
If there is only one physical interface on proxmox node then you can
configure one switchport on cisco side as acces/trunk-port - for

proxmox side:

auto vmbrxxx
iface vmbrxxx inet static
        address xxx
        gateway xxx
        bridge_ports xxx
        bridge_stp on
        bridge_fd 3

cisco side:

interface GigabitEthernetxxx
 description xxx
 switchport access vlan xxx
 switchport mode access
 no vtp
 spanning-tree portfast edge
 spanning-tree guard root
