I intend to buy a new router, this one in particular.
It says, it supports 802.11n protocol, so it could allow the transfer speed up to 300 Mbps between wireless devices.
Strangely, the WAN speed is limited to 10/100 Mbps.
Obviously, I intend to use the Internet through Wifi, but if the device can support only 100Mpbs on wire and the Internet is coming through a wire from the ISP (the ISP provides 500Mbps), I guess, the incoming Internet speed will be limited to 100Mbps.
Am I correct?

Yes, you are correct that the WAN facing speed will inherently limit your access here. However 100Mbit wired is likely to be significantly faster than 300Bbit wireless, so do not worry about it.
Just to explain that a bit. Modern wired Ethernet is point to point. Each device will get full speed. Wireless is a shared medium and has significantly more overhead. That means that it you place your computer right next to the router and if you are lucky then you may get up to 300Mbit though the air (minus overhead for useful data transfer). If you move further away then wireless speed will drop significantly. Also, if you use two wireless devices at the same time. (e.g. two computers downloading something from a fileserver) then both will share those 300Mbit, effectively halfbinf useful speed. (Mind you, if both are using the network, not just if present on it).
