Proxmox VE Networking Setup for Small Homelab – VLAN vs Single Bridge: Advice Needed

I am planning to improve the network setup for a small Proxmox VE homelab & wanted some advice from more experienced users here.

Right now the setup is quite basic with a single NIC and a standard Linux bridge configuration. It works fine for simple testing, but I am starting to look into VLANs and separate network segments for different services like storage, management, & VMs.

One concern I have is how people usually structure networking when they move beyond a single host setup. For example, is it better to keep everything on one bridge with VLAN tagging or separate physical NICs for different traffic types?

I have also noticed that hardware choice often affects these decisions. In some hardware discussions I follow through Tech Distributor, including Apple Distributor-related setups in Dubai, people often mention that network flexibility becomes more important than raw CPU performance once the lab grows.

Would be good to know what best practices others are using here, especially for home lab environments that might later scale into multi-node clusters.
 
I myself run my homelab with a VLAN aware bridge as this makes it easy to add vlans on the fly.

Say you want to test iscsi, Ceph etc or any other thing, it makes it easy to segregate traffic to what is what just by changing the tag on additional virtual bridged interfaces.

You will however need some sort of L3 routing such as a L3 switch or a virtual routing appliances for them to talk to each other.
