Boy, you don’t have much space to work with here.

Obviously, you should replace your garage door. There are charming wood garage doors with windows that would give your home some character. Search for samples here on Houzz or just google them.

After you get a new door, you can decorate around it with much larger modern lighting and a new paint color. (Maybe it’s my personal prejudice, but I don’t think the blue is doing you any favors.) Then, how about replacing the porch railing to complement your new garage door?

The fact of space being so tight necessitates the use of plants that comply with the plan. Left of the garage is fairly large shrub. Start turning this into a small tree form so that its bulky part, the canopy, will eventually be over your head where it can serve like a protective umbrella. Near the walk would only be a few upright trunks that do not occupy much ground space. To train it into a tree, make its overall shape similar to a sugar cone, where its tip has been embedded into the earth at the exact place the shrub grows. Trunks and foliage come up through/within the main part of the cone but nothing sticks outside of that shape. After it has reached 8' or more feet tall, you can let branches and foliage spill outside of the shape as if they were a giant blob of ice cream overflowing the the cone. Over time, starting at the bottom of the plant, remove branches, twigs and foliage so that only the bare trunks remain. You can do this to 50% of the plant's total height. (At any time of year, but early spring is the optimum time. Near the end of the growing season is the least optimum time.

Plant some low growing annuals, perennials, or groundcover below the tree. (Pick one, not use all three.) See if you could do the same thing at the right side of garage door.'

See if you could replace the uppermost garage door panel with one that has a bank of windows in it.

Along the narrow path to the front door, I'd ditch the hedge and replace it with low growing annuals, perennials, or groundcover. Since it is long, you wouldn't necessarily need to keep it all one thing for the whole length, though you could if desired. It could be a strip of multicolored impatiens, or a strip of variegated liriope, It it could have color at the beginning and end while the middle run is groundcover. For the blank wall, consider some flat, outdoor art decor. A flag stretched in a frame would work. But there's not room for plants or anything else to stick out into the path.

Thank you both for the comments! Yardvaark, thanks for the visuals. You both have convinced me to look into replacing the garage door.

Does anyone have color suggestions? Or at least, do you think I should go for a light house color with dark garage or vise versa or something else?

Also, my husband really likes the idea of screening in the front porch so that we can sit out there, get some fresh air, but not worry about Texas mosquitos. I like the idea functionally, but not sure about curb appeal. Thoughts?

I would suggest a medium value, grey/taupe range house color so that there is some contrast with the white trim. As it is now the white barely stands out against the light blue. If you screen the upper balcony, the railing behind the screen might be a dark color so as not to stand out, but disappear (if your screen is black).

You might be able to swap out just the upper panel of the garage door. also, you may be able to add hardware trim to the door.
