Just to add to my other comment, rocksmith is awesome if you have the reflexes for it. Otherwise, songsterr is great too. For learning strumming patterns I’d say relax your wrist and make sure your strap height is comfortable. I keep mine raised quite a bit to be able to hit high frets with ease. A lot of guitarists will disagree with me but use a thin pick and light strings.

Also, as I said in my other post adjust string action and practice everyday. I’ve been playing since I was a teenager and I play all styles of music. My forte is advanced lead stuff but my advice works for rhythm guitar as well. I’d say if your goal is rhythm you may be drawn to thicker picks, thicker strings, and lower strap height, but it’s really about what feels comfortable to you.

Also, if you have any interest learning fingerstyle you may want to start on a nylon string guitar. I used a guitalele at the beginning and the difference in comfort blew my mind. Now I only play steel string acoustic when I need to record fingerstyle acoustic stuff, but there’s a reason nylon strings are great for beginners.

If you need more advice about anything else guitar related just hit me up. I love passing down my knowledge.
