Welcome to Chordie Donatifamily!
I'd be checking out the Public Books section for beginner tunes to start with. There are a lot of three and four chord songs out there that would not be too difficult to master. Electrics are a bit easier on the fingers for starting out, but lend themselves to power chording and other variations that don't sound as good on acoustic. Volume and distortion hides a bunch of minor errors that allows one to gather up some "bad habits" that can be hard to break later if you find yourself playing acoustically.
The time to work on proper fingering and posture is day one! learn everything correctly and you don't suffer the cramps, sore tendons, and other little things that can reduce your enjoyment of making music. There is a lifetime of pleasure hiding in that chunk of wood and wire, so keep on playing.... it gets better and better!
Take Care and once again Welcome to Chordie!
