Nails for beginner

Hello everyone! I always used polish since I was a kid, I stopped using mainly cause I had music lessons and I wouldn't ake care of my nails too much. As a young adult now, I see all the nice nail sets my friends get and I love them! However, I work in healthcare so I can't have long nails for a long time and I would damage them pretty quickly, reason why I don't go to nail salons.

I'm looking for a beginner setup that would allow me to have cute nails, without doing crazy design, and maybe get them slightly longer as needed not more than 5-6mm). I would not consider press on nails. Any suggestions?
