Are you dipped in the Apple ecosystem at all? Might be worth it to get ApplePay and AirTags setup so you can keep tabs on the actual physical wallet betterwith AirTags and use ApplePay to minimize the amount of movingcards in and out creating opportunities for loss.
Wallet cases can be helpful if your phone has one that is designed for it on the market
All of my banks even my small credit union let me lock the cards and also order new ones in the app and one updated my cards in Apple Pay so I could have a card in the meantime through Apple Pay. Very helpful for the places that accept it.
Maybe consider getting one of those zippered folio type wallets that you keep at home or in your car (one stable location) to be the master card storage place and get a wallet case for your phone for the most important common cards you need to keep on your person at all times. Get that AirTag and keep it in the folio, then use the wallet case for your phone as you go about everyday which houses your iphone which you can track in itself because its an iPhone or whatever
