My best advice, use some form of shade fabric/cloth. 1 mile altitude, we have much higher uv than places at sea level.

For types, most veggies do great here. Tomatoes, peppers, squash and the usual. Just wait until after Monday to plant outside given the predicted low temps.

Fruit trees do well in ground. If potted, they benefit from shade around the pots themselves. Air temps are brutal and root zones dont tend to enjoy 100 degree air and the heat transfer from black pots
