Hello, so I think your strawberry plant looks healthy. As far as the fruit, that sunken spot on it could be a few things. Possibly a sign of fungal issues like black spot. It is only 1 fruit that has the issue? If so, you can be sure to watch new fruit to see if they're showing the same syptoms while growing. I grow strawberries as well and similar symptoms show up on my fruit when they have moisture on them for too long. This will cause the sunken spot on my fruit.

Your peppers look good. Black streaks are very common on green peppers. Some diseases are possible, but I doubt that as your plants appear to be healthy. Almost all my bell peppers and banana peppers get little black streaks. The little blossoms yellowing and falling off could be a sign of a few issues. If weather or temps have been changing it can cause the plants to drop their flowers. Pollination can be an issue too, but I dont think so considering your other plants have some good looking peppers on them. Too much fertilizer can make flowers drop too. Stress in general can be the culprit for your issue.
