I normally say, use the labels from the case. That is what the user
sees. But if this RDK does not have case, then maybe lan1-lan8 would
be better, to match the silk screen. And then call port9 sfp1?

Pretty simple. You need a node about the SFP itself:
sfp_eth3: sfp-eth3 {
compatible = "sff,sfp";
i2c-bus = <&sfp_1g_i2c>;
los-gpios = <&cpm_gpio2 22 GPIO_ACTIVE_HIGH>;
mod-def0-gpios = <&cpm_gpio2 21 GPIO_ACTIVE_LOW>;
maximum-power-milliwatt = <1000>;
pinctrl-names = "default";
pinctrl-0 = <&cpm_sfp_1g_pins &cps_sfp_1g_pins>;
tx-disable-gpios = <&cps_gpio1 24 GPIO_ACTIVE_HIGH>;
tx-fault-gpios = <&cpm_gpio2 19 GPIO_ACTIVE_HIGH>;
};
If you don't have any of the GPIO, just don't list them.
And in the MAC you need to reference the sfp:
sfp = <&sfp_eth3>;
Given that this is a marvell device, you might also need some comphy
configuration in the MAC node:
phy-names = "comphy";
phys = <&cps_comphy5 0>;
