Great topic idea! Here are some of mine, I'll add links later:
Heat resistant cooking gloves. These are basically oven mitts, but because they're gloves, you can keep them on while cooking. I've gifted a few pairs of these and everyone loves them!
A percussion massager is great for getting out muscle knots. Foam rollers too.
Collapsible creates for the car and around the house - mine are made by InstaCrate
A refillable oil sprayer so that you can buy any oil you want and evenly coat a pan. Great for searing and air frying
Stainless steel pots are amazing. IKEA sells a set that's around $50. Totally dishwasher safe, heat tolerant, just all around easy peasy
