What are the different ways to play four note chords on a guitar?

There are several ways to play four-note chords on a guitar. One common method is to play them as barre chords, where you use one finger to press down multiple strings at once. Another way is to play them as open chords, using a combination of open strings and fretted notes. Additionally, you can play four-note chords using fingerstyle techniques or by arpeggiating the notes individually.
