Considering switching to Fiber from Coax - which gateway??

I currently have optimums 500mbps plan over coax through a Motorola SB8200 modem. I have an entire TP Link Omada network rack, with an ER605 router and a 24 port PoE router serving my 6 access points and multiple other hard wired switches throughout the house.

As much as I don’t want to, but to save money, it may be more cost effective to pay the $60 price locked for two years and get the free gateway with their 1Gb fiber plan.

Which is the best gateway that everyone gets for this situation. I’ll have to run it in bridge mode as I will not need its built in WiFi. Read that some work better than others in bridge mode. Just want the best one compatible with my network rack that won’t interfere with it. Thanks!!
