One beginner thing that seems to work for me at low-stakes tables is from these boards: pricing your turn when you have players behind you.

So you get a flop that gives you a 4-flush or a OESD. If you make a minbet or 2xBB bet, a lot of the tables will just call the minbet, easily giving you +EV odds. Even when people decide to get "aggressive" they often just hit the "Raise" button again, you will still give you your odds. A lot of the people on beginner tables don't think odds, and see a bet of 2xBB as a serious move rather than thinking of a pot-size bet.

So this may be conservative when you could be pushing closer up to odds, and you still have to watch out for the better flush or the higher straight, but it's a starting point.
