That would be a neat trick since the CPU port(s) are only gigabit.

In my opinion the best option is to use only the SFP+ port for WAN and LAN (VLAN trunking) with a managed 10Gbit switch.
And not to use the strange switch construction of the R9000 (which is difficult to configure) at all.

That is where my confusion lies. It looks from the diagram that there are at least (2) 1 gig CPU port(s). One currently linked to LAN default vlan1 and one linked to WAN default vlan2. On top of that there is apparently a separate CPU port for the SPF that is of unknown speed assumed to be 10gig as the port is rated SPF+.

I take it you are saying that these 2 ports can not send combined data like say 2 bonded ports in the switch can?

It just strikes me as odd that data can come in the wan port (ie.5) @ 1gig and simultaneous go back out to the switch from the CPU through lan port (ie.0) @ 1gig and yet not be a able to enter the SPF+ port at 2G and exit the (2) 1gig ports at 1 gig each.

Interesting idea. I'm not familiar with the details of trunking. I have a bit of trouble visualizing that. The firewall filtering etc. would still be processed by the R9000 CPU; the information just wouldn't pass through the internal switches?

This is not difficult to configure.
In the “networking” tab, there is a “Tagging” field at the top where you select eth0 and create two VLANs for eth0 (for example VLAN3 and VLAN4)
Then two virtual VLAN interfaces are created (eth0.3 and eth0.4)
For example, we take eth0.3 as the WAN interface and select this interface under “WAN port assignment”.
eth0.4 is then taken as the LAN interface and bridged with br0

In the managed switch, one port must be configured as a trunk tagged VLAN3 and VLAN4.
VLAN3 is forwarded to another switch port to which the modem is connected (or the ONT)
VLAN4 is forwarded to all other switch ports - the LAN devices are then connected to these ports.

All routers with only one CPU port use trunking see: https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=335568

Here is another example of how to create VLAN interfaces on network interfaces: https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=334342&start=5

of course this runs through the router's firewall why wouldn't it?
