If I am understanding you correctly, you are having trouble with the "double tap" of the Touch ID models right? This operation was much easier on the smaller iphone SE. They probably designed it for that design(iphone 4-5S) due to its smaller size that allowed one handed operation and then carrying it over to the current SE design(iphone 6-11) is probably not ideal for that form factor(thinner and rounder). I believe the FaceID models solve this by having you slide the app up slightly to then select between it and any other open apps or go back to the home screen. Maybe that would work better for you? Also, this is just my opinion but like I mentioned, the iPhone SE Gen 2+ uses the last gen design language which started back in 2014(iphone 6) and has been gone from the main line for years now. It always felt super slippery and prone to dropping(too thin and those rounded edges are difficult to grip) which is why I held onto my iPhone SE Gen 1 until the new iPhone 12 came out. This is just my opinion but maybe you should go to a store and check out their other models.
