If you truly want to preserve the gloss / finish / shine of the clear coat, and reduce the risk of getting swirl marks, then
stay away from Automatic car washes.
It definitely takes more effort to keep cars cleaned / detailed yourself, but it can be a LOT easier and faster if you have the right products and right techniques (ie Easier waxing with more friendly waxes)
For
Cold Winters, Rinseless washes can be excellent (if you have a low to medium level of grime).
My favorite is the
Optimum No Rinse Wash and Wax - I have used this for years with excellent results, and can clean a car and SUV with
only 2 Gallons of water in the garage, away from freezing wind and death.

For Hand Washing, you can either pay someone or do it yourself.
I personally use an
electric Pressure Washer + Foam Gun + Blower (for drying).
I will sometimes use microfiber mitts after foaming to get at heavier grime areas not removed by pressure washing, and then quickly rinse + Foam again.
For water spots and extra shine, I then followup with
Duragloss Aquawax 951 (spray wax) between hand waxes.

I wax the cars at least 2-3 times a year with
Synthetic polymer waxes / sealants. Not carnauba.
Currently using
Mothers Synthetic car wax

Exterior windows get treated with
RainX a few times a year
Interior windows get cleaned with
Invisible Glass
I also use
RainX Brand wiper fluid which does an excellent job by itself keeping a coating on the windshield.
Boggles my mind why most dont spend the extra $1 for this amazing product, and instead run their wipers at a frenzy with each rain.
I also second the recommendation of Paint protection film. (front hood, mirrors, front roof, headlight lenses, etc)
I buy large rolls of 3M film on amazon / ebay, and then cut them down and apply myself - but I also paid a hefty price of blood / sweat / tears learning to do this somewhat competently.
