I had Eero Pros in the past as well and really liked the plug and play easy setup.
That said, Peplink APs support mesh but I don’t believe supports hardwired backhaul like Eero.
The benefit with Peplink mesh is extending your network wirelessly.
So you’d have to hardwire an AP close to your office ISP demarc then mesh the second AP somewhere in the middle of the home.
Rule of thumb is mesh point should be half way between your source and destination.
But hardwired APs will perform better. But more labor involved in running POE cables.
If you can do a site survey of your wifi signal strength with 1 AP centrally located vs 2 might give you better idea on placement and quantity.
I use inSSIDer and Netspot on Windows.
