Rb3011 and 2.5Gbps Internet connection

Hello, I have a RB3011UIAS-RM as my router at home connected to a Starlink router in Bridge mode. We are getting FTTP soon (goodbye Elon Musk!) and the expected speed will be 2.5Gbps. In the UK the ISP's primarily provide Ethernet to the home owner rather than PON. I am no expert when it comes to network although I make things work (VLAN's, ubiquiti AP's Integration, pihole as dns running on docker on a different device). My question is, can I benefit from this speed at all using my router? In my ignorance, I am thinking of link aggregation from ISP router to my MK router or a capable 2.5Gbps switch between the two routers and all LAN cables connected to said switch. Or is upgrading the router the only option? If so, would a RB4011 be the right choice? Can you, educated people, shed some light on this, please?
