I always mulch around the base of tomato plants, both to preserve moisture and to discourage disease and competing weeds.
As strawberries are perrenials, they will want a special, dedicated spot in the garden, that won't be tilled the next year. Spread some kind of clean mulch around the berry plants so that the berries do not rest directly on the soil. That way you should have no problem or less problem with fruit rot.
Don't plant the tomatoes and the potatoes too close together, and pay attention to their location, so as to avoid planting in the same exact location year after year. That cause a problem with disease build up in the soil.
Plan on using succession plantings. Kale, broccoli, snowpeas for example get through very early and can be followed with green beans, peppers, okra, etc. that will mature later in the growing season. I would plant okra in the area between snow peas, and the okra will be small but growing when the snow peas are finished. When sketching your garden arrangement be sure and group plants according to early, short season, vs. later long season. That way you can plan on a good arrangement in the garden, and can use interplanting and/or succession planting to maximize the things that you grow and to maximize the length of your growing season.
Never wet the foilage of tomatoes when watering as that encourages disease.
IMO most perennial herbs are easier to give care and maintain in planters. Would save my garden space for annual herbs. Aloe may be a better candidate for a container plant.
These are just a few somewhat random thoughts, way early in the morning. Hopefully, you will get some other input.
Consider using drip irrigation as it saves both water and time.
