Do you really need MLAG? (the 2x10G bandwith?). If not, just use 2 simple switches (Mikrotik for example) and in Proxmox use an active-pasive bond, with default interface in all nodes to the same switch.
Since we are now on SSD OSDs only, and our aim is to be able to add more OSD nodes, yes: I think we should aim for more than 10G bandwidth.
So go for 40G. LACP will not give you 2x10 magical bandwidth doubling.
BTW: I am using mikrotik 10g switches and they have great value. BTW2: if you use Proxmox you do not need LACP you can use linux round robin support that has the same performance of LACP and it does not require switches support.
