Many vendors make routers which have 4G modem which then send out a WiFi signal + have Ethernet ports.
In rural areas the ADSL prices started climbing up a few years ago and most moved to cellular (60 euros for 21Mbps ADSL vs 25 euros for 50Mbps 4G). As of recent fiber connections are getting good in rural areas as well, so people are switching to fiber (40 euros for 100/100Mbps, 60 euros for 1000/1000Mbps). People who have both 4G router + fiber are quite rare.
In my experience some channels on 4G are quite ossified and during peak times you might even get a better throughput on 3G.
