I usually use redwood and have used cedar also.
It is a nice wood, and will last if installed correctly.
Using PT under for joist and post and girder is a good idea.
Screws in decking are best.
I would avoid paint.
I would use a oil stain or oil base sealer.
Paint tends to trap moisture and thus cause rot.
I have taken apart many a fences that were painted, and the interior is
rotten since the moisture
stayed inside the wood and was encapsulated. the sun come out and steam
heats the picket.
Wide deck board spacing is important.
Avoiding "sandwiching of boards is important"
I worked with a forensic architect, and learned many things as to why
buildings fail, and that included
decks. He was quite obstinate about allowing wood to be "in air' and avoid
too much contact to other pieces.
I know this is hard to describe. It is basically not sandwiching materials.
Pressure washing decks is a good idea, since it clean out debris.
Oiling once in a while after pressure washing is good too.
The wood can still breath, and the pours get filled with oil.
Too much oil is not good. It will come out in the heat of the day.
I could go on.

For the purposes of this discussion, I would list my options as pressure
treated or cedar as these are generally the only readily available wood
options and I do not care for the look of composite or plastic decking
boards, at least not in this application. It is my understanding, from the
research that I have done that either application, pt or cedar, will require
some annual maintenance and thus the added expense of cedar may not be worth
it in the long run. My take on what I have read is that if left completely
alone, with no upkeep, the pt will likely last longer? Since I don't plan on
taking this approach, how much maintenance, realistically, should I expect
on pressure treated decking and can I, with this maintenance, keep it
looking pleasing and fresh? What is the best option for treating the
surface? Can I use a paint or colored stain and expect it to hold up to
moderate foot traffic?
