There are countless pros, and zero cons.
So.... no brainer decision there ;)
Best to just grab a couple low or moderate light plants to start with, get comfortable with them, and go from there. Don't go overboard buying fancy lighting or super substrates, or any of that. In a 10g you probably have the two screw in lights? Just go to Walmart, Home Depot, Lowes, etc and get a dual pack of 10W GE Daylight (Color temperature 6500K) CFLs (compact fluorescent lights).
Get some stem plants, and just toss them in to float around. It's that easy ;) Floating plants grow faster, which means they improve water quality more, and they easily get plenty of light being so close to them. Plus they provide shade for your fish, which almost all fish prefer.
For fertilizer, all you need is a comprehensive one, like Florish. Use a babies medicine dropper to dose 0.8 mL once a week, and you're done. A bottle of this will literally last you for years since the dose is so small.
Algae is the biggest concern people have with plants. But to counter that, just put your lights on a timer so they are only on for 8 to 10 hours a day. Start with 8 hours a day, the two 10W CFLs is pretty bright for a 10g.
