If you want an easy to use project to get a map and feed to different sites like adsbexchange and flightradar24, I would recommend checking out: https://github.com/sdr-enthusiasts https://github.com/sdr-enthusiasts/docker-adsb-ultrafeeder https://github.com/sdr-enthusiasts/docker-flightradar24 https://adsb.im/home

There is a good community out there on github and discord that have flight tracking as a hobby. In addition to ADS-B there is also voice radio transmissions from aircraft (airband) and text messages (ACARS) etc. If you get hooked there is lots of different things to tinker with.
