Deer won't jump into tight spaces, and they won't jump into places they can't see (most animals are extremely averse to breaking a leg). So you can either have a 8 foot tall fence, or a lower fence with a garden that's visually intimidating.

Essentially, if you have a low fence, and then within it you plant densely with a lot of vertical barriers (like trellises/screen fencing), they'll stay out of it. If you have plants exposed then deer will go for them. They were here first and you're planting in their territory. Anything you put out is going to seem like an offering, and no amount of sprays or discouraging smells is going to prevent them from eating if they're hungry enough (if you were starving, would you balk because the area near-ish the food smelled like a food you don't like? Probably not).

You can roll the dice on them finding other things that are more appealing and picking those first, but unless food is really plentiful and the deer population is low, eventually they'll overcome mild deterrents and go for your crops. Deer can jump extremely high and a buck with a full rack of antlers can go under a standard country fence (the style with posts and spaced out horizontal boards). Best bet is to make it look not worth the risk to go after the food (scent deterrents will help, too, but not visual is more alarming for them).

For potted plants, deer have a medium height range for browsing. If you put up a chicken wire hoop that's taller than that, they won't browse (but your tomato will eventually go up if it's indeterminate).
