Good layout for Ethernet magnetics
The priority is to optimize the routing of the tx and rx pairs. Run the pair 3-6 better.

I assume the magnetic has common chokes built-in, then the terminations to the unused pairs do not have much impact. So the routing of that would have the lowest priority.

Use thicker traces for the node where all the terminations go to the capacitor.

I remember 100Mbps Ethernet has a bandwidth of around 80MHz, so the wavelength over a trace would be like 2m. The short connections do not behave like transmission lines and it is not critical to get the exact trace impedance.
