Home Access Points Setup

Hi everyone, I'm about to move in a 3-story terraced house.

There's a fiber hub at ground floor.

Each level has Ethernet outlet.

I'm thinking about setting up a access point or router on each floor via Ethernet outlet.

And I can switch to 3 routers seamlessly.

Correct me if I'm wrong.

Connect fiber box to Ethernet switch so that all Ethernet outlets will have internet access, right?

How can I achieve above?

Thank you.
