Hello, I'm a newbie at this sort of thing so please forgive my ignorance. I'm just trying to understand what would be my best setup for a brand new apartment I'm just moving into. It's a new build, and so it is connected to fiber optic. There is one connection in the living room (on the ground floor) for the fiber optic. The apartment itself has two levels, and so I would really like some connection linking the ground floor to the 1st floor (European floors :) ) where our bedroom, possibly my media server and potential home office will be.

I don't do heavy gaming or anything, so I don't necessarily need super fast everywhere, I just need at least an ethernet connection (I think) up to the 1st floor to connect to my server and to plug into my computer. So I'm thinking about trying to get just that connection run. Is this probably the best idea instead of trying to run the fiber optic up to the top as well? I've read that fiber can be tricky and finicky and I really don't think I need a guarantee of the top top speeds when ethernet should be fine.

Then, I can also plug a separate wifi router into that upstairs connection so we can get good wifi upstairs, correct? Or what would be the best way to unify the network? Thank you all for your help.
