Get a descent Hakko soldering station. The cheap irons are serviceable but the tips don’t last and tend to total out the iron - they’re serviceable to learn, but not a long term investment. If you go this route, buy 2 and find one with 2 tips (1 attached/1 extra) in the package, so you arent stuck when the tip burns up within a few uses. The secondary iron can be kept as a backup or discarded. Walmart sells a disposable iron with solder and an extra tip and solder for $10. Don’t do this long term - it will cost you more.
For solder the Radio Shack solder is excellent. I have a few rolls I got when the store here closed since I may not be able to find another one easily again. Stick with that brand but keep a backup on your mind just in case.
