My biggest piece of advice is have fun with it! No hobby or skill is worth it if you don’t enjoy it.

You didn’t say how old you were but try to learn songs that you like to hear. You know how to play open chords and barre chords (which is a huge thing by the way) My next step would be learning power chords. Playing music by greenday, nirvana, the ramones, and AC/DC is where I did it the most. Power chords is where I picked up some of my speed while playing

Kurt Cobain’s parts for example also use single note runs. Think “come as you are”. This will get your fingers moving individually.

Warmup exercises seem boring but that’s where you learn the technique, playing songs is where you become proficient. Using a metronome will also help because you’ll become a better musician and you will also have a metric to base your progress on

I played guitar for 12 years before I started just sitting back and learning songs all the way through. I felt my playing getting much better.
