Arduino + LoRa (need help with devices and libraries)

I want to use arduino with LoRa to setup a mesh network. My purpose is to send and receive short text messages (for emergency communication), sensor data and probably commands to automate electrical appliances. It's just a rough idea at this stage and I'm really not sure which specific devices to use. Is it a good idea to use RFM95 with arduino? I also need help deciding which libraries to use for mesh network setup. I can't seem to find any viable tutorial after looking for about a couple of days. Please provide links to tutorials if you happen to have found one.
My best regards.

edit: I'm also interested to go in-depth with radio frequency technologies and I would be very glad to know articles or courses that will help me.

If you want to go 'in-depth' then a course of a few years in college is one way.
