Ethernet did not stagnate. Ethernet on UTP did stagnate due to reaching the limits of the technology, but Ethernet continues to advance over fiber.

For 10 Gbps I find it simpler and cheaper to use fiber or DACs, but motherboards don't provide SFP+, only RJ45 ports. Over 10 Gbps copper is a no go. SFP28 and above would be nice to have on motherboards, but that's a dream with almost zero chances to happen. For most people RJ45 + WiFi 7 is good enough, computer manufacturers will not put SFP+ or SFP28 for a small minority of people.
