My buddy wants to build some planters and benches for his deck. He
has Norm's plans:

So we stop today at a random lumber yard to get a price on Cedar.
Price for 'A' grade (only pin sized knots) minimum 8' length
2x4 $3.73 LF
5/4x4 $2.28 LF

I have no comparison but that seems a tad bit expensive.

Any other options other than Cedar? This will be outside year round
and will be exposed to salt air from the bay.
