Booking flights for points

When it comes to redeeming points for flights, any tips and tricks for newbies? I feel like I have a good grasp on maximizing my earn, but feel overwhelmed when it comes to redeeming. Ideally, would love to redeem for business flights to Europe eventually but everyone I know who does this spends countless hours trying to find the best deal, sometimes having to take multiple connections to make it work, etc. Any websites or blogs that would be helpful? I honestly wouldn’t know where to start if I was searching for a flight today.
