I’m far from an expert as I only paint my nails occasionally, but I’d recommend getting a color you like as well as a clear polish. I generally do two coats of color and then a top coat of the clear polish to add a bit of protection. I’ve never bothered using alcohol to wipe away oil, but it may help prevent peeling afterward, idk
Can’t speak on any preferable brands, I just grab whatever, but I will say to avoid gel polish as this requires UV treatment to properly harden. Found that out the hard way after I woke up with fuzz from my blanket stuck to my nails :(
It’s simple enough even as a beginner but do expect some mess, specifically paint on your fingers around the nail. Still haven’t figured out how to paint them without doing that but the excess generally peels off in a day or so, especially during/after a shower
Side note - if you can’t decide on a color, just go with black. Goes with anything and looks good on any skin tone
Sorry I don’t have more advice but I hope I could be of some help! Best of luck <3
