When it comes to line, there's no wrong or right. But instead, it's much more situational.
Mono: cheap and helps to prevent damage to the reel, but is also much thicker than braid which means less line in the spool. Has a moderate visibility.
Braid: more expensive and thinner, so you can fit massive amounts in your spool. However, it wears out much faster and has a higher impact in your gear. High visibility.
Fluoro: the most expensive but also the thickest. Suits well if you're planning on fishing smaller cautious fish like bream. Has a very low visibility but also wears out quickly.
If I can suit 130+ meter of line in the spool, I would use mono in most of my setups. It's cheap, lasts a long time and helps you to save a bit on repairs. But as I said, in the end it's up to you depending on what you find the most important.
