A Proxmox cluster with Ceph pretty much won't work without 10Gbps.
It'll slowly fail and all your data will get lost. Ask me how I know.
(Also, you need at least 4GB memory dedicated to Ceph on each node... Another compounding lesson learned)

It's more that Proxmox has a weird niche laying between both enterprise/small-medium business and also homelab infrastructure.
Ceph is designed towards the former where 10Gbe fibre and hosts with a boatload of RAM is fairly commonplace.
My problems were a result of not paying close enough attention to those requirements and just hoping it would work on small micro PCs with 12GB of ram.
