My gig internet connection on intel tops at 900ish, vs the 10G Marvell Aquantia gets 1270, not much will take advantage of that aside from large downloads, or heavy workload, which is what I take advantage of mostly. Your modem and router must support at least 2.5gb/s. if your networks is all 1000, then no difference. But, if you got fiber, then your fiber box should have at least a 2.5g port to take advantage of what you're paying for. Also, your Encore has wifi 6 which when i tested on my encore with a wifi 6 router hooked to 2.5g modem, was getting 1200 gbs download. I stick to wired, though. This is al;l using cat6, no sfp needed.
