I've been playing acoustic guitar for like 5 years now. I imagine chord digitation would be fairly similar with electric guitar.

You have to press the strings with the very tip of your fingers. But I really mean the very tip, so that the sides of your fingers don't touch the strings you don't want to press; when this happens, it causes weird vibrations in the other strings that make your chords not sound as-clean. You also have to press the strings with enough force, otherwise there's gonna be weird micro-bounces between it and the fret that aren't gonna let it sound clear. If you struggle pressing the strings too much, maybe you need softer strings (strings that require less force when pressed to emit sound, like nylon strings compared to metal strings).

A common thing I see happening with beginners is that they can't "open" their hands enough to digitate the chords. Their hands don't seem to be as-flexible, so they trip over themselves a lot; wich is completely understandable, flexible hands are something you acquire through practice. Just try to "open more" your hands, so that you don't touch strings you don't want to touch as you play.

Start with simple chords. Nobody's gonna start with f'ing jazz chords. The first thing you can learn is (chords) Am-Em or Am-E sucesions on the first two frets; that way you're gonna acquire flexibility and your hand is gonna get used to the positions.

Also, there's is a good chance your chords don't sound as-well because the distance between the strings of your guitar is too little, your fingers are too big, both, or your strings are too big and you need thinner strings. In either of those cases, you can either keep practicing pressing the strings with the very tip of your finger, or get a guitar with a bigger neck width.

Cheers!
