First, a website that will answer most of your questions about canning & preserving and has hundreds of recipes:
http://www.sbcanning.com/
I will cook just about anything from SeriousEats.com or CooksIllustrated.com. Canning on SeriousEats, here:

You don't need a subscription to do a search on CooksIllustrated.com, but will to actually get the recipe. However, much of their content has already been republished in the web.
Recipes: A few of my favorites:
Bloody Mary Mix:

Canned, Marinated Peppers, for mild to medium peppers:
https://cookingupastory.com/how-to-can-marinated-red-peppers-video-recipe (I
never seem to make enough of these
, they are that good)
Sweet & Sour Hot Peppers:
http://www.eatingwell.com/recipe/252965/sweet-pickled-peppers/ (I've used this recipe to pickle green beans, sliced jalapenos, sliced carrots; I think you could pickle just about any veggie with it.) To hot process it, just prep as stated and, instead of refrigerating, process it in a hot water bath for 10 minutes.
Red Pepper Relish:
https://www.thespruceeats.com/homemade-sweet-bell-pepper-relish-3059161 (I used my Aleppo flakes instead of paprika.)
Fresh Tomato and Caramelized Onion Jam Recipe:
https://www.seriouseats.com/recipes/2013/09/fresh-tomato-caramelized-onion-jam-recipe.html
Pepper Vinegar, from Cooks Illustrated:
6 ounces tabasco, red Fresno or red jalapeno chiles, halved lengthwise
3 cups distilled white vinegar
4 teaspoons granulated sugar
2 teaspoons salt
1 teaspoon whole black peppercorns
1/4 teaspoon red pepper flakes
Pepper vinegar is spicy. For a milder vinegar, remove the seeds and ribs from the chiles.
Pack chiles in clean 1-quart glass jar with tight-fitting lid. Combine vinegar, sugar, salt, peppercorns, and pepper flakes in medium saucepan and bring to boil over medium-high heat. Pour brine into jar, making sure chiles are fully submerged. Let cool completely. Affix jar lid and refrigerate for at least 3 weeks before serving. Pepper vinegar will keep, refrigerated, for up to 3 months.
For the Freezer:
Roasted Tomato Soup:
https://www.foodnetwork.com/recipes/tyler-florence/roasted-tomato-soup-recipe-1917339 (I prep it through roasting the tomatoes, then portion and freeze it for later use.)
Red Sauce: halve any ripe tomato you have, put on a sheet pan cut side up, toss in some peeled garlic cloves and any fresh or dried herbs you have and like, salt and pepper the lot and drizzle with olive oil. Slow roast at 225F until the tops of the tomatoes look dry but the meat is still moist. Put through a food mill on the coarsest setting you can. Portion and freeze. To save space, I use FoodSaver bags and freeze them flat. Same for the Roasted Tomato Soup.
If you have a Kitchenaid with the power port on it's front, invest in a KitchenAid FVSFGA Fruit/Vegetable Strainer with the Food Grinder Attachment for it. If you sign up for Williams-Sonoma emails, they'll eventually send you a 25% off offer, with free shipping. I have a few attachments for mine, but use this the most.
