fiber is better than ethernetcables which is preferable to wifi ( at least for almost all es-folks, possible exceptions simply prove this rule ).
ethernetcables may carry also pollution from the modem into the pc into the monitor and mouse plus keyboard.
modems with wifi disabled are still sources of emfs, although much less strong of course.
grounding a modem ( e.g. via usb-outlet, connect outside plug ) can reduce fields towards a landline phone connected to it.
regarding frequencies in the lower MHz range ethernetcables can be shielded in areas where one spends a lot of time.
cat-7 cables are an idea, running the cables through metal pipes shields much better.
steel pipes could increase electrical fields ( unless grounded ), aluminium tape is a bit less effective and can get cracks.
aluminium pipes are cheap and usually abundantly available in the trash which is my favourite place to get stuff.
electric stoves emit electric and magnetic fields, by far the worst is certainly "inductive" cooking, by all means to be avoided.
some people may argue that all heating up of food is a crime, but that is a whole other topic.
