WiFi Access Point vs Extender: Which Coverage Method Fits?

An access point creates WiFi from a wired network connection. A range extender usually receives WiFi from the router and relays it farther; some models can switch to wired access point mode.

A wired access point usually makes more sense when you can run Ethernet to the area. An extender is easier where cabling is impractical and the router signal remains usable at its location.

It needs an upstream connection to the router, either wireless or wired in access point mode. Without that connection, it cannot provide access to the router’s internet service.

Yes, if the network design and configuration support both. Place and configure each device to avoid unnecessary overlap, and follow the relevant manufacturer’s guidance.
