Ideal SFP GPON to replace Calix 813G-2 for MikroTik Hex S, considering ISP limits?

Hello, I’m looking to replace my Calix 813G-2 GPON device provided by my ISP. I want to replace it with an SFP GPON module and connect it to a MikroTik Hex S router. However, I’m unsure about the type of SFP module I should get. Unfortunately, my ISP isn’t able to assist me, so I’m seeking advice on my own. Any recommendations or guidance would be greatly appreciated.

My ISP supplied a Calix 100-05609 10 (Assembly 300-02923-11). I had to set the interface, route, and VLAN for my static public IP.

I’d like to get a Leolabs ONT to play with.

My ISP does scan for software versions and updates accordingly. Check with them first.
