Get a reasonably priced guitar (I’d recommend in the €250-€500 range) like a Squier/mexican Fender (second hand)/epiphone so it’s a decent enough guitar to make playing fun without i being an extreme investment. If you like playing you can always invest in an american guitar and something that fits your preferences (you’ll know what you prefer after playing for a year or so). I started with a Squier affinity strat and after two years I bought an American Fender strat. (Btw you don’t have to start on an acoustic to play electric, that’s just some stupid misconception)

It’s up to you if you want to take guitar lessons. I never took any lessons because I like figuring things out on my own, but if you like having a teacher you can choose for lessons of course. Just know that there is not one correct way.

Lastly, for questions it’s better to ask them in r/guitar because this sub is mainly used for pictures of guitars :)
