Mikrotik allows a single bridge to be connected to all Ethernet ports and WiFi interfaces.
Is there an advantage to separating the Wireless and the Wired, such that there is a dedicated bridge for each?
Meaning, there are two bridges in total: a “bridge-Ethernet” and a “bridge-WiFi”.
I would use vlans and one bridge…
Advantage might be seemingly spmpler setup. But there are plenty of disadvantages, most important one is possible loss of HW offload of wired traffic and thus increase of CPU load and/or decreased throughput.
…
Right, that is also the advice here:

Though isn’t two bridges the minimum configuration?
One bridge for LAN.
Second bridge for WAN.
Minimum configuration is one bridge. In most configuration WAN requires single interface which can either be off-bridge or member of common bridge (properly configured).
Actually, minimum configuration is no bridge … if all interfaces are used for connecting different networks (so device is router-only, not bridge/switch).
