Hi Rob,
Great that you're an active family and wanting to get into climbing. There's SO MUCH info these days for the beginner climber, so you could start by having a look at this:
https://www.thebmc.co.uk/get-into-climbing-indoor-climbing-bmc-magazine-for...
Then check out lots of the BMC starting out videos. Go to one of the many walls in Sheffield and take some instruction on how to belay safely. You'll also hopefully meet people who could be helpful. Join a local club. Hire a guide for a day to get a taste of gritstone climbing with some basic instruction to make sure you can pursue it safely on your own. You're obviously well placed to enjoy some of the best climbing in the country, with sport and trad a'plenty on the doorstep. Bouldering is easy - get a pad or two, and head out to one of the many Peak bouldering venues and have a go. Familiarise yourself with the local ethics and best practice. You'll find this in a guide book. If you head to, for example, Outside in Hathersage, you'll find many guide books to choose from, but the staff there will help you pick the best one for you. You can get one which covers the whole Peak, bouldering, trad and sport, or more specialised guides, depending on what you think you're most likely to do.
If your teenage kids are willing to talk to you, let alone hang out and do fun active stuff together, it sounds like you've won the game
Good luck, be safe, have fun.
