If you want to play rock, I would forget the acoustic route.
Get yourself a proper, rock guitar. These fall in to two fairly different types. The Les Paul type and the Stratocaster type.
Play them both. You need to know which one you are comfortable with.
The Les Paul type has a thick body, generally made of heavy wood. You know about the weight if you gig with one! The neck is generally thicker. The fingerboard is wider with a flatter radius. Better suited to bigger hands and thicker fingers. Bending is slightly easier as the scale length is a bit shorter.
The sound is more suited to 'heavy' rock due to the humbucking pickups, heavy woods and straight through necks.
Jimmy Page mostly plays a Les Paul.
The Stratocaster type guitar has a thinner body made of lighter woods. The body is chamfered for added comfort. The neck is generally thinner with narrow string spacing. It better suits slender fingers. They always have a tremelo (or 'whammy bar') that allows you to de-tune the strings as you hold a note.
Stratocaster guitars usually have single coil pickups which are not as 'heavy' sounding as twin coil (or 'humbucker') pickups.
The sound is much more flexible and can do The Shadows to Deep Purple.
Dave Gilmour (Pink Floyd) mostly plays a Stratocaster.
Richie Blackmore (Deep Purple) also plays a Stratocaster.
Both to great effect IMO.
There is a middle ground though. Look up the
Epiphone ES335. It's a semi acoustic that can be played unplugged for practice but can also punt out a decent rock sound when plugged in. The playing feel (or 'action') is the same as a regular electric.
Mostly jazz and blues players use these. B B King and Chuck Berry used a derivative, the ES355.
Make sure you have a go on all these types before you buy.
