How Should I Play This Hand

My original thought was to call down post flop and treat as a bluff catcher.  However, the board kept getting worse for me and better for the perceived wide range of the blind.  I have not seen the opponent play enough hands to have a read. Against a default opponent should I:

C-Raise on this coordinated flop?  SPR is about 10 so I dont want to get it all-in, correct? If I C-Raise what is my turn and river action if called?  I know episode 213 suggests to c-raise on a coordinated flop, but the SPR is around 10.

As played, how many streets do I call on this coordinated board?  Was I correct to fold to the river bet with any 7 to a straight, flush possible, trips possible?

Thanks for your help.
