I think you should get a cookbook of 30 minute meals from a reputable source, such as this one: https://www.amazon.com/Best-30-Minute-Recipe-Cooks-Illustrated/dp/0936184981
Then go through and flag recipes that would work for your family, and make a list of those, then slot them into your menu.
I also think you should also resign yourself to having a plan b with the kids - if something new doesn’t turn out you’ll just give them a peanut butter sandwich or whatever and it won’t be the end of the world.
When I am concerned that the recipe I want to try might be a miss with my husband, I’ll generally make sure to have a favorite of his as another meal that week, so the week overall will be a culinary success for him and I won’t feel guilty if the new dish disappoints.
I found Cook's Illustrated to be an experience and confidence builder. Similar to Serious Eats, they'll try various approaches to a recipe, find what works and what doesn't, and post the resulting final recipe. Their 'Best 30-Minute Recipe' is a great place to start, as the recipes are uncomplicated and you can have a winning result without having invested 2 or 3 hours on an uncertain outcome:

Tons of other similar cookbooks and web things around. Tray Bakes from Nigella Lawson for example. Fix it and forget it crockpot stuff
There are several cookbooks/websites that break recipes down into what to do, how to do it, and why it works. 'Cooks Illustrated - The Best 30-minute recipe' covers a lot of ground and is a simple place to start: You can't get too fussy if you're only cooking for a half hour. They've got piles of other specific books too - best international, slow cooker, light, vegetarian, etc.
'The Food Lab - Better Home Cooking through Science' and the 'Serious Eats' website by Kenji Alt-Lopez are a lot of fun. He'll take a dish and make it the way you've always heard it should be made, then break down what works, what doesn't, why it doesn't, and what's the best way to make whatever it is. The bottom line recipe is there if you want to skip the process.
The Food Wishes series on YouTube, by Chef John, is really excellent at walking you through a recipe in a light, relaxed way. He captures his mistakes and leaves them in the videos too, to remind you that some mistakes don't matter, and some can be worked around.
Anyways, it's a process. Find a few recipes, make them, expand your repertoire at your own pace. You're going to be eating for a long time, and you don't need to know how to do everything at once. Experiment with what intrigues you, and if it doesn't work out, there's always pizza!
