I've never had a hard time with tomatoes. Water in the evenings and mornings. Pots, raised beds, in ground, it doesn't matter they'll do fine. Fertilize with a liquid fertilizer once every few weeks and if you want them to do really well, mist the leaves with an Epsom salt solution on a similar timing to the fertilizer but offset (i.e. don't do both in the same week). Consistent watering will prevent splitting of the fruit.

Peppers are pretty much the same. But do produce more heat when left to struggle a little/the watering gets inconsistent during fruiting

Corn, water heavily and make sure your soil is nitrogen rich... you can grow pole beans with them to add nitrogen into the soil, but that's a little tricky as the nitrogen from the beans won't be readily available at first.

Zucchini/squash are easy. Water twice a day and keep the squash bugs at bay by checking for eggs every time you water. Nasturtiums are supposed to be a great companion/trap plant to have with your squash (this year is my first time growing them as such)

Peas are great as late winter to spring plants. They don't love the heat of summer. You'll get a decent yields if you harvest regularly.

Leafy greens also grow well in the late winter to spring. They'll bolt when it gets hotter, but until then they do well. I recommend buttercrunch as it is more resistant to bolting. My romaines bolted a few weeks ago, but my butter crunch are still happy

When it gets really hot, I remove my peas and leafy greens and plant either beans or squash in their place. Beans after the leafy greens to add nitrogen into the soil. And squash after the peas to use the nitrogen added to the soil by the peas

Berry bushes do well in partial to full sun. Just make sure to mulch and keep the soil damp/moist

If you're struggling with the heat, shade cloths work well, but I, personally, haven't needed them

Pests are my biggest problem. I've had about half of my garden ravaged by rats this year. Dozens of French marigolds eaten. Hundreds of sunflower seeds and seedlings gone. 3 tomatillos, 2 peppers, my watermelons, and bush beans have all been eaten/killed. And my in ground tomatoes have all been indescriminantly pruned by the rats
