Hey, I completely understand your situation, old medications and worn-out supplies can really make a first aid kit useless when you actually need it. From my experience, the best approach is a hybrid: start with a solid pre-made kit, then customize it with extras that fit your activities and group size.
For example, I picked up a well-organized kit from FlareSyn for my camping and vehicle kits. It had all the essentials bandages, gauze, antiseptics, and even some advanced items like splints and burn care but I still added a few extras I know we’ll need based on our past trips. What really helped was keeping a small, separate bag with personal medications and over-the-counter items that tend to expire faster.

One tip I’ve learned: rotate consumables regularly, and keep a checklist in each kit so when something expires, you replace it immediately. That way, your kits, truck, car, camping are always ready to go without scrambling for missing items.
