You might be better served on the Pinkbike Forums. The responses here will be more from the XCO crowd and will push towards climbing ability and less travel. I’m an XCO guy for racing but also own two longer travel bikes for training/fun. If you are really riding park and gnarly trails then follow your instincts and go with 150-170mm travel up front. You will have a lot more fun and the bike is really built for the abuse it’s going to receive. If you aren’t racing uphill then weight is really not something to worry about. Even a top of the line Scott Ransom or Yeti SB150 will be a +30lb bike.
You can get an aluminum 29" wheel Ibis Ripmo AF for $3,199. It’s a great spec for the price and will eat the harsh trails up all day long. 160/147 and DW Link makes it climb well enough for what it is.
Whatever you do avoid XC bikes for what you want to ride. All of the bikes you mentioned would be fine candidates but I wouldn’t go less travel. If you have steep steeps one thing an Enduro bike should have out of the box is 4 piston calipers and bigger 200/180 rotors.
