Settle on planes hill on coast. That start has low production and a bunch of useless food tiles that you dont need, plains hill will double early production. Your going to waste a lot of time at your pop cap and charges clearing those marshes.
You also have access to a 4 yield tile right away, hopefull to the south theres another mountain you can grab a +2 campus. Theres a 4 food tile that you can upgrade to a 5 food in your second ring as well. Crabs also means +3 harbor. You also get access to that forest for a chop, if you can get a plaza there you can maybe get a +3 campus.
SIP just means your city will hit the cap faster. You can mine those hills, bit thats early charges you don't want to waste. Its going to be a pretty low production city either way.
Edit:also if you plaza the forest you can get a +4 harbor or a +3 hub on the other side of the river.
